And now for something completely different

Now, just because the first posts in this blog of mine have been rather serious doesn't mean I can't lighten up. In fact, I'm rather a funny fellow sometimes.

Here's a clip of a well-known lead actor of an American medical drama. Perhaps this may give you a different perspective of him.



As a comparison, here's the same clip which was made for the pilot for Fry and Laurie, a British sketch comedy show:



He's been on such great shows such as Black Adder (with Rowan Atkinson) and Fry and Laurie (with, obviously, Stephen Fry). I highly recommend those programmes as well.

Oh British comedy. Nothing quite like it!

Disease, Heart Attacks and Grizzly Bears: An Introduction to Mathematical Biology

As I've mentioned in a previous post, I'm currently completing a master's degree in mathematical biology. Since this isn't the first thing people see opening up the newspaper or gossip magazines, I thought I'd give you an idea of what exactly mathbio is and what it entails.

The short version is that mathematical biology is exactly what it sounds like: using mathematical methods and techniques to solve problems in biology. What kinds of problems, you ask? Almost all areas of biology can be found in a mathematical context, from ecosystem management to immunology to pure evolutionary theory. Pretty much any area you could study in biology has had someone, somewhere look at things from a mathematical perspective.

Personally, I think that this is a great thing, both on the biological side and the mathematical side. The biology community gets new angles to view problems from and hard quantitative results that can be the basis for experiments and further hypotheses. The mathematical community gets motivation for problems and for more pure mathematical research areas. And everyone gets solutions which could potentially save lives and better the understanding of the world we live in. Mathematical biology is undergoing a revolution of sorts, which began earlier in the 20th Century, and whose fruits are being realized now at larger scales, and not just in the ivory tower. Let me give you a few examples to illustrate this.

Take mathematical epidemiology. In Canada, this seems to be the largest subfield of mathbio (but I could be wrong). This area looks at the study of infectious diseases and epidemics and tries to model them using equations. The goal is to better understand how epidemics begin, persist, and what can be done to prevent or constrain them. Using mathematical models allows researchers and medical professionals to consider different scenarios and look at specific factors and their impact, without any risk or harm to the general population. For example, I've seen models looking at factors causing and preventing Mad Cow disease in livestock, of HPV (human papillomavirus ) and the effectiveness of potential vaccination regimes, and of the spread of HIV in parts of sub-Saharan Africa. These are certainly real issues with real consequences, and solutions are being developed by applied mathematicians and health researchers.

Or perhaps you'd be more interested in mathematical ecology. Ecology is the study of how species interact on a macro level in ecosystems, and what affects the population growth or decline of species. Modelling predator-prey or competing species interactions are classic examples of mathematical biology. One of the most studied examples is the dynamics of lynx-hare populations in the Canadian Arctic. The hare is prey for the lynx, and as one population changes, so does the other. Salmon are an example of competing species. Salmon farms are usually situated near wild salmon habitats, so they use some of the same resources, and there is a chance that either the farm or wild salmon could wipe out the other, each case with negative consequences. I have seen papers and presentations of both ecological situations. Even more interesting is the fact that such ecological modelling has yielded some rich mathematics, specifically for the fields of dynamical systems and chaos theory. Perhaps this shows nature has much to show us about the intricacies of mathematics.

If neither of those took your fancy, perhaps you'd be interested in mathematical physiology and medicine. This area sees the mathematical modelling of physiological processes and medical treatments, and attempts to use math to gain a better understanding how the human body works and how we can better heal it. One big area of research here is tumour development and growth. Here, mathematics and related methods are used to study how tumours grow and sustain themselves and how they can be stopped or at least controlled. Related to this is the study of cancer and how it begins at the cellular level. I have also seen research done on causes of heart attacks and irregular heartbeats and how a to design a better kidney dialysis machine, both using good old mathematics. This I think could be the most promising area of mathbio research, since it could benefit almost everyone by furthering our understanding of medical treatments without using real patients or scarce medical resources. And again it could also give more insight to underlying maths that are used to model such problems.

I should mention that my research isn't really in any of these research areas. I'm more into evolutionary game theory and the evolution of cooperation, which is a pretty cool topic in itself, loosely based the question "Why bother helping others out when you just free load instead?". I'll give more insight to this question and my rears later on. But I hope that I've at least shed a little light on this thing called mathematical biology. But there's lots more than what I've written above. From tropical diseases to why we have sex, a mathbio researcher has used math to understand it.

"I'm Thinking of Going to Grad School"

So, you're thinking of going to grad school. I think that's great, because in some ways, being a graduate student is terrific. However, in some ways, being a graduate student is a bit of a crappy career path. It really depends on your motivation, your career goals, and your opinions on education in general. It's not a trivial decision.

Basically, my opinion is this: if you don't like school or "academia", don't go to grad school. You probably won't like it, and will likely hate it. If you enjoy school and are good at it, you might like grad school, but there are other considerations to be had too.

So, without further ado, here's the breakdown of reasons to go and not go to grad school:

Reasons to Go:

• Pursuing an academic career: This one is pretty obvious. If you want to have a job in academia as a professor or researcher, you'll need to start you journey in grad school. Doing some postgraduate work is a good way to figure out if going down this path is right for you. Talking to other grad students or professors is also a good idea. The academic life is something of a calling, but look into it if you think it's for you.
  
• Gaining experience for a particular career: While a Bachelor's degree is a good thing to have on your resume, there are a few jobs that typically look for more. For example, some jobs in finance or investment banking look for individuals with Master's or PhD degrees. Some administrative positions in education require at least a Master's. And I've also heard that you'll be taken more seriously as an author with an advanced degree. In some disciplines such as mathematics, graduate level education is much different from undergraduate, and employers may be looking for something specific. In all of these cases, the knowledge and skills you'll acquire in graduate work will be helpful, and be put to good use.
  
• Continuing previous work done: This is perhaps an unusual reason, but still a valid one. You may have done some work for a professor or researcher during your undergrad, as a research assistant, programmer or TA. If it went well, and there's still more work to be done, maybe they'd take you on as a graduate student. You gain a good reference and an advanced degree for your resume. They get continuation on their work and an established collaborator. For some people, this is a win-win situation. I personally think this benefits everyone involved, and can foster strong professional relationships.

Reasons to Not Go:

• "Couldn't think of what else to do": This is hands down the worst reason to go to grad school. Indifference is a terrible thing to have in academia. If you're not "into" your research, it will show. It is hard to be motivated and take initiative to read current journal articles on narrow topics such as pair approximation methods in lattice-based population dynamics models. It'll also be hard to prepare for tutorials for dozens of first year engineering students, some of which are wondering why they lost marks on that one question they knew they got right, and others of which get up and leave noisily as you try to demonstrate how to compute a matrix inverse. Believe me, if you really turn your nose up at either of these situations, perhaps graduate work is not for you.
  
• No interest in research: If you don't like the idea of doing hardcore academic research, perhaps consider another career option. Research is the order of the day as a graduate student (and in turn as a professor). If you're writing a thesis, you must come up with some original research to publish. If you're taking a course-based degree, you will still have to read academic papers and books. In any case, graduate study is much more independent than undergrad. Even if you like the teaching aspect, disliking research will not make for a good time in grad school.
• Money: It has to be said: If you want to make a lot of money, don't go to grad school. You will be poor. Even if you score a major grant or scholarship, you will make less than entry level wages. People who want a corner office on the top floor and a posh urban loft typically don't go to grad school. They go to the so-called "corporate" world, right after college or university. Wanting to make a lot of money isn't bad and I'm making no judgments here, but I can say that you probably not enjoy the grad school life. I certainly know people who went to work right after their first diploma/degree, and they couldn't be happier for it. You just have to know yourself and what you want. The upside here is that your career prospects may improve if you have an advanced degree, so you may need to do a cost-benefit analysis to see if it's worth a few years of have a "lower" income.
  

This list is by no means exhaustive, but hopefully it paints a picture of what the grad school life is like. I can say that I think I make a good decision for myself. On the whole, I love what I'm doing right now.

"So, what are you going to do with that?"

This is probably the most annoying question that I get asked on a semi-regular basis. I'm finishing a Master's degree in applied math, and I'll be out looking for work or more school in only a few months. Clearly, I'm asking myself this question as well. But answering this question is tricky sometimes; it's not easy to be specific, and sometimes my response may appear flaky. The result is some awkward situations when "what I do for a living" comes up in oh so casual conversation. Also, saying that I'm a graduate student leads to some funny reactions. Here's why I think this is the case.

First of all, people really don't like math. Some people would rather boil their hair and drink the broth than talk about math. They hated it, had a bad teacher experience, failed some courses or just plain "didn't get it". This means that saying "I'm a math student" or "I do research in math" kills social interactions almost instantly. People just aren't interested. That's why I sometimes say I do mathematical biology, because at least some people like biology. Or that I research the evolution of cooperation, of why animals and people cooperate with one another. That at least goes over well sometimes. But in general, mentioning math is cocktail party suicide. I think this is really unfortunate, but such is life.

Of course, saying I'm a graduate student doesn't fare much better. I think that individuals who aren't in or have done postgraduate work get a little confused by this. They hear "student" and think "poor, unemployed, possibly lazy, but working towards something good hopefully". But there's also the "graduate" part in that statement. Most individuals in the non-academic world went to school at least partially to have better job prospects, perhaps even pursue a professional career like law or medicine. They certainly didn't go to school for the sake of going to school (right?). So when they hear "graduate student" I think some "working world" individuals think I went to school to go to more school, to avoid "working for Man" as it were. "If I'm in school I don't have to grow up and get a real job and be an adult, so why wouldn't I stay in school?" must be my line of reasoning.

Well, it isn't. Why I went to grad school will likely be a topic for another day, but I can say that avoiding "the Man" was not a large factor. Instead, I'll offer my insight to what a graduate student "does" in terms of it being a job (which it is). In some ways, it's like being an apprentice; you learn the in's and out's of research, what's going on in your field of study, and general professional conduct of being a professor/researcher/university teacher. For example, I'm currently writing my thesis, and it needs to include certain things and particular details. With this, I'm also reading up on current research and being exposed to what's happening in the field at the moment. I'm also a TA for a course in linear algebra, which involves marking tests and preparing tutorials each week for a section of around 75 students. Lastly, I engage with other students, professors and researchers on a regular basis to discuss other academic issues and research areas. These are typical duties of a grad student, and add up to a pretty involved "job". I also find time to have fun and prepare for a wedding in less than a year. I enjoy my current line of work, even with its downsides.

So in a nutshell, that's "what I do". What I'm going to "do" with this experience is obviously not as clear. I will likely be looking for work in the "real" world, and likely job positions are things like software developer, actuary, some kind of "analyst" or even teaching at either the high school or college level (university level is not looking good at this point for me). But those are just ideas, and I'm sure there are other things out there for me. Really I'd like a position that let's me do mathy stuff all day, so something quantitative. I'm also comfortable with computers and programming. However, I'll just have to see what I do with my Master's degree.

Greeting to the Digital World!

Hello everyone. I've decided to take a giant leap into the depths of Web, and put myself out there. Who knows, maybe someone will even pay some attention to me.

A bit about myself. I am Canadian, and currently completing a Master's Degree in Applied Mathematics at a southern Ontario university. I'm also engaged, and going to be married in a little under a year. Such opens the story of this blog. With these two things going on, I've been learning a lot of about the academic world, the "working" world, and the interaction between the two. I also really like mathematical biology, mon spécialité , and cooking, and my fiancee, among other things. This blog is about these things, and all other things that are, in a word, me.

Hopefully this will be good for me or someone else. If not, well, at least it's better than sitting around doing nothing (or baking too much...).
