Recent happenings in Professor Winget’s research

July 2018: My undergraduate research student (Cindy Gallardo) and I are using the computational chemistry program Gaussian to predict Surface Enhanced Raman Spectroscopy results (SERS) and Infra-red (IR) spectroscopy results from biologically relevant molecules, in order to understand those results further, and to aid scientific progress within the fields we choose to study.

Specific Projects:

1 – Probing the relationship between lipid composition in the body and brain diseases such as depression, with Infrared (IR) Spectroscopy

2 – Early diagnosis of certain types of cancer, such as breast cancer, with Surface Enhanced Raman Spectroscopy (SERS)

July 2018: Cindy Gallardo and I went to learn as much as we could, and to meet lots of interesting people, at the annual conference of the MERCURY (Molecular Education and Research Consortium in Undergraduate computational chemistRY) group. At Furman University in Greenville, South Carolina

 

July 2018: Oral presentation at the 2018 Biennial Conference on Chemical Education (BCCE) at Notre Dame, Indiana. Infrared spectroscopy (FTIR) and POGIL are combined in physical chemistry laboratory modules

     

April 2015: Poster presentation of experimental physical chemistry research at the national meeting of the Materials Research Society (MRS) . In San Francisco, CA.   In-situ SERS Detection of Catalytic Reactions by using Au-decorated Truncated Nanocubes

July 2017: Final report submitted to the National Science Foundation (NSF). I was Co-PI on a grant of $195,997, awarded to purchase a research-grade FTIR spectrometer and to enrich IR spectroscopy learning through inquiry-based activities.
