About Me:
I was born in the beautiful Caribbean island of enchantment, Puerto Rico. I lived there with my family for a short time until we decided to move to Miami, Florida. While there, I graduated from Sunset Senior High School in 1995 and proceeded to go into the business world by becoming a registered stockbroker at Prudential, Inc. and UBS PaineWebber, Inc. In 2002, I decided to return to school and then graduated with a Bachelor’s degree from Florida International University. After my college education, I headed north to Midland, Michigan for an internship at Dow Corning Corporation. I began my graduate career at the University of Florida in the fall of 2006. I knew from the start that the only thing I could be was a Yostie where I can live out all my fundamental dreams of high field asymmetric waveform ion mobility spectrometry (FAIMS) and mass spectrometry (MS).
Research Interests:
The focus of my undergraduate research was the development of a universal GC/MS/MS method for the detection of ignitable liquid residues (ILR) under the advisement of Dr. Jose R. Almirall. This research involved the detection and extractions of small amounts of ILRs from fire debris evidence. The detection of ILRs can be difficult because of the considerable loss of these compounds during the fire, extraction techniques that are not the most sensitive, co-extraction of interfering products (IP), and because analysis techniques often provide low discrimination. The main purpose of my project was to optimize a general method that may utilized by examiners to improve current analysis of fire debris without significantly altering the workload or time required for analysis. My graduate interests have been mostly focused on the basic development and characterization of a portable explosives detection instrument which utilizes and maximizes the technology of High-Field Asymmetric Waveform Ion Mobility Spectrometry/Mass Spectrometry (FAIMS/MS). Exploring the fundamental and practical issues of curved electrode geometries and novel waveform approaches is also of interest. The marriage of FAIMS and MS will be operated with an atmospheric pressure ionization (API) source which requires to be fully characterized with each particular geometry while applying it to explosive detection. Continual collaborations with the Chemistry Department Machine Shop have been vital to this side project. All this mentioned above falls under one big priority of me attaining as much knowledge as possible to help me better understand and analyze my compounds
