Chemistry (including Biochemistry)/Graduate Studies


Dr. Robichaud, my name is Granit Studenica, I am a 3rd year Chemistry student at York University in Canada, with an interest in atmospheric chemistry. I'm passionate about chemistry, I enjoy it and would like to see myself at least in a humble way making an important contribution. However, I'm a little unsure about graduate studies and the cost associated with them. From your experience, is pursuing a Masters or PhD worthwhile and beneficial given the added costs that go along with them?. Thank you for taking the time to read my message. Best Regards.

Dear Granit;

In the USA, PhD degrees are perhaps the opposite of a guarantor of employ. I do not know how the situation stands in your fair Northern provinces.

Would you prefer to ask and answer your own chemical questions? Do you prefer working alone or on teams? Are you content with a predetermined path or would you prefer to blaze your own trail?

If you like working alone, if you like uncertainty and big scores, if you are firm in your confidence and have the ruthlessness to win, and if you don't mind long hours and moving from city to city every few years, then academia may be your thing, and a PhD is for you.

If you like working in teams, if you don't mind working on other people's questions, if you aren't married to a particular idea or disease, then industrial chemistry may be your thing. This may or may not be more stable in terms of geographic area, and this will require you to be flexible with the occasional layoff. Much of the time a Master's is preferable for this path.

I don't have any guarantees, Granit. All you need is one job. Ask yourself where you're happy. If you don't know, do internships and try things out; get experience.

Good luck. :)

No homework questions, especially ones copied and pasted from textbooks. I will answer questions about principles or give hints, but I do not do other's homework. I'm comfortable answering basic biochemistry, chemistry, and biology questions up to and including an undergraduate level of understanding. This includes molecular biology, protein purification, and genetics. My training/inclination is primarily in structural biology, or how the shapes of things affect their function. Other interests include protein design, protein engineering, enzyme kinetics, and metabolic diseases such as cancer, atherosclerosis, and diabetes. My chemistry weaknesses are that I do not know organic or inorganic synthesis well, nor am I familiar with advanced inorganic reactions. I will attempt quantum mechanics and thermodynamics questions, but primarily as they relate to biological systems. Furthermore, I cannot tell you if a skin photograph is cancerous, or otherwise diagnose any disease. I can tell you how we currently understand the basic science behind a disease state, but I cannot recommend treatment in any way. Please direct such questions to your medical professional.


I hold a PhD in Biomedical Science from the University of Massachusetts Medical School in Worcester. I specialize in Biochemistry, with a focus on protein chemistry. My thesis work involved the structure and functions of the human glucose transporter 1. (hGLUT1) Currently I am a postdoc working in peptide (mini-protein) design and enzymology at the University of Texas Health Science Center in San Antonio, Texas. I am in Bjorn Steffensen's lab (PhD, DDS), studying gelatinase A and oral carcinoma.
