Portrait of Mary Tran-Gyamfi

Research Interests

In the past 10 years, Mary Tran-Gyamfi has worked on many different projects. In studying plants, algae, fungi and yeast, she has been able to understand the complexities and the roles that differing organisms can play in helping to build Sandia's bioenergy program. She works in the bioconversion of algal carbohydrate and proteins, engineers and screens yeast to produce terpenes, and runs algae testbed experiments in three 1000L ponds to test algae growth under varying conditions.
