Week 3: SCIEX and CRISPR/Cas

I really enjoyed the field trip to SCIEX this week. I think that it is interesting to see how companies optimise their operations and also as a biotech company, how they continue to innovate and improve in an iterative fashion. They take into account not only customer feedback but even things like walking distance to optimise associate work efficiency.

As for the science technology, I think that its great that they are looking at forecasting the trends for mass spec analysis instead of just waiting on their customer demands. Having the best of both worlds in the QTRAP system is great for the future when we might be looking to analysing greater amounts in a shorter period of time, we will need to rely more on qualitative screening.

For lecture and reading, I enjoyed the review papers assigned to us. Gave me a comprehensive understanding of the mechanics of CRISPR/Cas9 system as well as the future modifications that can be done to it. Prof Liou did a good job in reiterating the reading material again, as well as the difference and advantages between RNAi and CRISPR. I think that RNAi has a lot of potential but it’s right to say that there is a lot of difficulty in getting it approved due to the off-target effects. Patisiran is the first RNAi approved as a therapeutic, so I think that there is way more that can be worked on this area.


Dealing with rejection

Today, the School of Computing (SOC) sent my rejection email for my Business Analytics Minor application.

I can’t describe how I feel other than to say I feel a tinge lost. Ever since I decided I would take the huge leap to switch my track to Business Analytics minor two semesters ago, I always thought I had a plan ahead of me. Looking at it, I’m not sure if that means I can no longer take any more business analytics mods. If that’s the case I will be more disappointed because I actually enjoyed the BT1101 mod I took the last sem, just that I really regret not investing more time into it.

Moving forward, I emailed someone to ask about it. Hopefully, it is a yes but I’m prepared for the no. This sem has really hit me with a load of reorganizing my initial study plan, so I’m not surprised if I have to do it again.

What I really hope is that I can move forward and continue to do better for all my other mods because I know this rejection is not the end for me, as much as it was an idealized scenario.

Learning from Failure: GWM Babes

“Concentrating on one thing at a time may be the single most important factor in achieving flow.”

– Hector Garcia Puigcerver

Okay, let’s start from the beginning. Around November last year, a friend of mine tagged me in a post from a fitness account doing a giveaway for a set of sports bra and leggings. I’m sure like many women who saw the post, I went “damn free sportswear if I just share this post? Sign me up.” And so was the beginning of something too good to be true.

Firstly, when you go over to the advertised link, the free activewear came with a ‘shipping fee’ of around 30SGD. Now, the e-shopper in me knows that shipping from China can’t possibly cost that much, and I’m sure it wasn’t coming from the US. So it was clear they were trying to make as much profit off this launch as possible, which I don’t fault them for. I do fault them for the fact that the made explicit promises time and time again for stipulated arrival time, but they never seemed to meet. It surprised me that even though I was one of the first few to make my order (my friend had an even earlier order number and she still received hers late), I was part of the very last batch.

The lack of transparency as to how they were deciding which orders got fulfilled, just floored me. By order number? No. By size? Maybe. They were sending out their orders based on which size was manufactured, and yet they weren’t following a numeric order within the size orders. Not only is it confusing but it just raises some questions as to the fairness of it all. Some Facebook users even questioned if they were pushing up orders of those who made enough noise. Highly disappointed.

All in all, I just think whoever was part of this team was way in over their heads, shooting in too many directions. They could have done some prediction as to the quantity that they were going to pre-order and maybe have some of the stock in first before launching their campaign. Even the way that the checking of orders was initially handles was a mess. Customers were encouraged to join a Facebook group for more updates when that is probably one of the most chaotic methods I can think of for themselves and for the customers. They later released an excel sheet on the suggestion from one of the Facebook members.

Just my two cents worth and reflection on this debacle of a launch.

My Parents Told Me No

“We are never in lack of money.

We lack people with dreams, who can die for those dreams.”

– Jack Ma

My father was outraged when I told him I would be going to Pulau Ubin for 21 days. My mother cried when I informed her I would be staying on campus for 2 years. All my life, my parents have been very protective of me, but that has not stopped me.

I was constantly berated by my parents for wanting to do things that they deemed “girls shouldn’t be doing” such as sports and outdoor activities. Even as I was about to enter University, part of me still felt like a small girl, scared and unsure of what I could achieve. At that point, I knew I wanted to change their perceptions of me, and their perceptions of what a girl could and could not do. And so began my journey to prove them wrong, to relearn and rediscover the kind of person I want to be. Although it was painful to see them angry hurt initially, I wanted to seize the opportunities in front of me and I still do.

While I continue to walk this path of self-discovery each and every day, I know what fuels me is my desire for adventure and challenges. These two areas breed discomfort and uncertainty, of which push me towards excellence. I can never be better than I was yesterday if I don’t choose to challenge myself and open myself up to opportunities for learning. Gravitating towards experiences that further my personal growth, I one day want to be in a position as an entrepreneur to inspire other ‘small girls’ to take control of their potential.

End of June reflection

“When work becomes play, and play becomes work, your life unfolds.”

– Robert Frost

July is closing in and there is merely a week of June left. What an eventful few weeks it has been, indeed. Besides the fact that I got to take a short trip to Taiwan, right after my finals, one of my highlights for my summer so far has been the completion of my two main projects.

NUS Kayaking has been a huge part of my life and completing Legs & Paddles 2019 officially marked the end of my time with them. I know that deep down, I’ll still be helping them out here and there, but I want to shift my focus on new land.

My time as an assistant mentor for the 0319 batch of LSA wasn’t easy. I wasn’t able to fully commit my time and energy to it due to some family commitments and at the same time juggling work, school and Kayaking meetings. It was hard for me because I know that I was not fully present for my mentees, much less present for myself to learn from the experience. Nonetheless, I was pleasantly surprised when D-day came and the event was generally a smooth success.

Upon reflection, I really do enjoy my roles in both NUS Kayaking and as an OBS assistant mentor. Even though I wish I could be doing more of what I do in those positions at work, I realize that some areas overlap and I learn even more things outside of what I do in kayaking in OBS. Interning at SCALE was initially just a means for financial security during this summer, but now I’m starting to see how much I can really learn especially about business development and event operations from here. I’m excited for the weeks ahead, and secretly hoping for more work.

5 Year Plan? Not yet.

I’m not sure. In the next two years, I know that I will be finishing my last two years in university but what about the next three? And in those two years alone I’m not even sure what is really ahead for me. About 5 months ago when I decided that I wanted to venture into entrepreneurship, I knew that it was going to be difficult. Here I am in June, my mid-year check-in and we haven’t made much progress. What’s wrong? Not enough time was intentionally spent on it. At the start, I was spending at least an hour of my day on market research but along the way, I got extremely distracted by my other priorities. The time spend on our side project started to dwindle. But I couldn’t stop thinking about it.

I’ve come to realize that in order to move forward, I should 1) spend less energy beating myself up on not “doing enough” and 2) continue to create realistic goals for me to complete each day, baby steps. As my lecturer once said, if you don’t start pushing the ball, how do you expect it to roll?

Since LNP and (very soon) Ubin Unite is coming to an end, I have less of an excuse for not putting enough time into my business idea. Honestly, I think it’s time for me to realise when to let go of my ideas too and start again at the drawing board.

What is your beachhead market? What’s their budget, urgency, priority, access?

Reflections of a Life Scientist: The Impacts of Cities on Epidemiology

The exponential establishment of cities throughout the globe in the last century is without a doubt a marker of our technological and societal advancements as a human race. Better infrastructure and improved healthcare, are just a few of the many associated benefits of living in a city. At the same time, we cannot ignore the negative impacts of the establishment of cities. In particular, with regards to the realm of life sciences, cities have been a huge curveball for all living beings, the environment, and not forgetting the scientists who study them. Cities have introduced a multitude of new factors for scientists to consider. In epidemiology especially, there are new challenges presented every day to the scientists who already have the difficult task of understanding the complex field of diseases and their transmission. This essay will focus on the challenges and changes that epidemiologists and other scientists in the field, like myself, face as a result of the establishment of cities in the past decade.

  In the field of epidemiology, studying the of risk factors of a disease or infection is crucial in understanding its spread. As scientists, we need to be sensitive about the factors that help exacerbate or proliferate diseases and illnesses within a population in order to accurately study its transmission and growth mechanisms. With the rapid establishment of cities in the last century, we have introduced into the equation a completely new set of risk factors– the urban environment and everything else that comes along with it. For instance, the establishment of cities has brought about a change in lifestyle for people, and epidemiologists are seeing an increase in noncommunicable diseases or lifestyle-related diseases as well as mental health issues (Hubacek & et al., 2009). While it is true that cities bring better access to healthcare and technology, this has greatly changed the trends of morbidity and mortality (McKeown, 2009). In many countries with booming cities, there is a sharp rise in the ageing population (World Health Organisation, 2011).

  There is extended morbidity despite the lower rate of mortality because people in cities are living longer, but it does not always translate to a better quality of life. In developing countries where more are moving to cities, more elderly are left without informal care from their families or relatives (World Health Organisation, 2011). On the same note, noncommunicable diseases exponentially increase with age, therefore the increasing elderly population in the world is not only a societal and economic burden but a challenge for scientists to keep up with too (Yoshikawa, 2000; World Health Organisation, 2018). Hence, epidemiologists are faced with a new understanding of how cities influence this new age of diseases.

  Where there are people, there is a chance to transmit disease; Cities multiply this effect by the hundredfold, by bringing people physically closer together. Generally, cities are characterised to have a higher population density than their rural counterparts. Hence, contact with another person is much more imminent. The high population density in cities increases the propagation of infectious diseases, including those that transmit by air, bodily fluids, water and other vectors (Lee, 1994; Monteiro & et al., 2006). Cities are at greater risk of spreading infectious diseases, not just because of their high population density but their greater connectivity with the rest of the world and other cities (Alirol & et al., 2011). With over 35,000 international flights in a day, Singapore Changi Airport was dubbed the most connected airport in the Asia Pacific region (OAG, 2018). Imagine the scale at which an infectious disease could be spread to the rest of the world from there. It could easily result in a global pandemic, similar to that of the various strains of influenza in the past (Pattemore & Jennings, 2008) and more recently, Ebola virus (Park & et al., 2015). Of course, that is why health organizations and governments worldwide are so wary of such an event happening (Barnes, 2018). The greater the speed of transmission of diseases within cities is important to understand and morphs today’s modern approach to epidemiology. As diseases evolve at a terrifying rate (Leventhal & et al., 2015), scientists need to look closely at cities and how they can more accurately model the transmission of disease based on human networks.

  In the face of urbanisation, epidemiologists cannot take for granted the state of affairs when it comes to diseases. Upon reflection, my approach to learning about the transmission of diseases has changed because of the establishment of cities, more so because I live in one. As mentioned previously, there has been a shift in prevailing diseases amongst cities, a rise in noncommunicable diseases and age-related diseases. In Singapore, the ageing population is a real concern. Projections estimate that Singapore may be the fifth most elderly populated country in a matter of almost 30 years (United Nations, 2015). This makes studying the epidemiology of ageing and its associated diseases, even more, relevant for me. I have become more sensitive to the risk factors in urban environments. I have also had to change the way I perceive research and my scientific method when it comes to dealing with the confounding effects of cities on my research in this area. Being in a city, such as Singapore, I get to enjoy the comforts of better infrastructure and in turn, better technology. However, I often do not notice the over-reliance on technology as a scientist in a city. Internet connection is a ‘basic necessity’ nowadays. And as a student, it is hard to imagine a life without it, let alone having to do literature reviews and research without the vast pools of e-libraries and repositories at my fingertips. Moreover, most modern laboratories in cities are well-equipped with air-conditioning and huge freezers to store cell samples, consuming “three to four times more energy than the average building” according to a study by Eades (2018). Therefore, in the laboratory, I try my best to be more energy-saving and environmentally conscious when carrying out my research. Trying as much as possible to use glass-stirrers instead of disposables ones, and doing simples things like turning off the fume hood when not in use, I choose to reduce the carbon footprint of my laboratory.

  As much as my research is important, it is just as important to try to reduce the negative impacts brought about by the establishment of cities. If not, scientists would just be adding on to the impacts caused by cities, and we already have enough problems to face as it is. With no sign that the growth of cities is going to slow down any time soon, we should be very aware of the novel challenges that studying diseases in cities pose. I strongly believe that understanding cities is vital to understanding diseases in the 21st century, and eventually how to control them.
