Amritha De Croos, PhD
OTA ID#: 101042
| Education Experience: |
BSc Hons, Biology, Dalhousie University, 1997 MSc, Biology, Trent University, 2000 PhD, Biology, Carleton University, 2003 |
|---|---|
| Focus of Study: | I am currently a post-doctoral fellow studying MAPK and cell signalling. I am pursing my research interests by studying how a stress affects the signal cascades that take place under exogenous signals. My research uses numerous biochemical techniques forcing me to stay up-to-date in biochemistry, molecular biology and microbiology. | Outside Interests: | Apart from science, I enjoy film, travelling and spicy foods! |
