Professional/Academic Experience

My academic background included coursework and research in evolution/ecology as well as biochemistry/toxinology, and this broad foundation allows me to utilize an integrated approach in both my teaching and research. I teach several graduate and undergraduate courses in biomedicine (Toxinology [Biology 565], Current Topics in Biomedical Research [Biology 556], Human Anatomy [Biology 341], Parasitology [Biology 333/533]) and vertebrate biology (Herpetology [Biology 335/535], Comparative Anatomy [Biology 345]) at 甜心视频app. As part of their training in Biological Sciences, many undergraduate students have participated in independent research in my lab [Biology 422]; several of these students were coauthors on peer-reviewed publications, and many have continued on in graduate and professional programs and careers.

Research/Areas of Interest

The general focus of much of my research is on venomous snakes and their venoms; however, particular research projects involve very different aspects of the biology of these remarkable animals, ranging from functional biochemistry to population molecular genetics to natural history/ecology. It is my opinion that an interdisciplinary approach to research can offer the best possibility of understanding an organism and mechanisms of its interactions with its environment, and so my research and that of my students utilizes this multifaceted approach. Below are elaborations of specific projects in progress.

A webinar produced summer of 2018 that discusses some aspects of venom composition and effects of these components on living tissues can be found here:  Reptile venoms - composition and action  Please note that figures and photographs are proprietary and copyright SP Mackessy 2021.
