Principal Investigator

 
Ana Caicedo

Ana L. Caicedo

Ana obtained her B.S. in Biology in 1996 at the Universidad de los Andes in Bogotá, Colombia. She left the lofty peaks of the Andes for the (flatter) environment of the Midwest U.S. to attend graduate school at Washington University in St. Louis; there she studied the population genetics of disease resistance genes in wild tomatoes and received her Ph.D. in 2003. During a postdoc at NC State, she carried out research on the evolutionary genomics of rice domestication and the population genetics of floral timing genes in Arabidopsis thaliana. Ana joined the UMass Biology faculty in 2006. Her current research interests include the genetic basis of adaptation, the genomics of plant domestication, and the population genetics of diversification within and between species (CV).

Graduate Students

 

Stephanie Craig

Stephanie Craig

Stephanie is now a Masters student in the lab.  She originally came to the Caicedo lab as an undergraduate to further explore her passion for genetics, and studied the effect of weed evolution on R gene diversity.  As an undergraduate, she received two Commonwealth College Honors Research Grants and was selected to be a part of the prestigious Junior Fellows Program her senior year. Stephanie now plans to wrap up her work on weedy R gene evolution, and begin exploring some of the bases for hybrid incompatibility in U.S. weedy rice.

 

Ian Gillis

Ian Gillis

Ian is a fourth year Plant Biology grad student with a BS in plant biology from the University of Washington Seattle. As an undergraduate he studied and wrote a paper on a Camellia colonial fungus, Seuratia Millardetii. He then rested on these laurels for many seasons before returning to the exciting world of higher education. Hitching a trailer on his car, with his cat sitting shotgun, he set off into the sunrise to find out what New England had to offer. Ian’s westcoast charm and caffeine fueled intellect secured him a place at the University of Massachusetts Amherst, and his interest in the processes driving evolution has brought him to the Caicedo lab. Ian’s specific interest is in how interactions between disparate organisms work and how they evolved.

Zhongyun received her B.S. in biology from Fudan University in China in 2011, She worked on rice for two years when she was an undergraduate student. She left her crowded hometown, Shanghai, to study her beloved field of plant biology in the beautiful town of Amherst. Zhongyun rotated as a PB student in the Caicedo lab in Fall of 2011 and has now decided to join the lab for her dissertation research.  She is extremely interested in evolutionary history of crops and various topics involving genetics and evolution of plant, and will be focusing on red rice evolution in Asia.

Technician

 
Sherin

Sherin Kanthi Perera

Sherin received her B.S. in Biology in 1987 at the University of Peradeniya, Sri Lanka. She has a Post Graduate Diploma in education too. For many years Sherin was a high school biology teacher in Sri Lanka. After immigrating to the U.S., Sherin volunteeered for a summer in the lab and got some hands on experience in rice phenotyping, DNA extraction, and challenging PCRs. Since then, she has been working in the lab as a techinician. Sherin's knowledge of rice growth and agriculture has proved to be a great resource for all, and her tasty Sri Lankan dishes are addictive.
