Academic Awards:

“Honor of Academic and Scholarly Growth for Accomplishments in Publishing and Grantmanship in 2007” from The Office of Academic Affairs of Hostos Community College
“Honor of Academic Excellence at Fall 2006” from Hostos Community College for successfully completing the Honors Contract Agreement.   

Areas of Expertise:

General Chemistry, Biochemistry, Breast Cancer, Drug Development, Antimicrobial Resistance.

Areas of Interest:

My areas of interests include: to study the effect of cigarette smoke condensate (mainly nicotine) and radiation-induced breast cancer progression among the minority population in the South Bronx and development of some drugs to prevent it. Also, analyses the structural alteration of non-steroidal anti-inflammatory drugs (NSAIDs) to use them as an antibiotic against drug-resistant pathogenic bacteria.
