 McNair Experience

I was motivated to participate in this program because I want to complete a PhD in Biophysics and obtain a research position at the graduate level, and this program offers help with applying to graduate school.

A Mathematical Model for Radiation-Induced Cell Carcinogenesis

§         Undergraduate research in the area of space science and biology.

§         The results were presented in the First Physics Congress, April 2002 and at the  EPSCoR Annual Meeting, May 2002.

Cell Survival Curves for Space Radiation

§         We developed and solved in a closed form a carcinogenesis mathematical model with n mutations and parameters, characterizing an equal number of different biological processes arising when a stem cell population is continuously irradiated with high-LET HZE radiation.

§         The results were presented in:

o   Junior Technical Meeting, March 2003

Insulin Fibrillogenesis Studied by Atomic Force Microscopy

  • In preliminary experiments that will eventually study the formation of fibrils (fibrillogenesis) in abnormal ataxin-3 proteins related to Huntington’s disease, we have used the Atomic Force Microscopy (AFM) to investigate fibrillogenesis in bovine insulin to determine protocols for sample preparation, structure measurement, and image analysis.  This leads to a proof-of-concept for the future ataxin-3 work.  Through a set of time-series measurements, we have succeeded in imaging insulin through different stages of fibril formation.

 

 

A Radiation Induced Carcinogenesis Model for Space Radiation

§         We continued working with the model of carcinogenesis developed and solved in a closed form, adding the TG-43 protocol.

§         The results were presented in:

o      NASA PR Space Grant Consortium External Advisory Board, February 8, 2005.

o     Investigation Day, University of Puerto Rico-Humacao, Humacao PR, February 24, 2005.

o      Junior Technical Meeting
, March 2005.
