At Intel, I worked as an EUV Lithography Engineer for 2 years. This role truly allowed me to demonstrate my technical expertise, my ability to analyze data to ensure good quality and productivity, and my drive to improve structural systems and methodologies. The EUV lithography scanners that I worked with are some of the most complex instruments in existence. I started this role with no prior knowledge but was able to quickly achieve the necessary technical knowledge.

This role truly allowed me to demonstrate my technical expertise, my ability to analyze data to ensure good quality and productivity, and my drive to improve structural systems and methodologies. The EUV lithography scanners that I worked with are some of the most complex instruments in existence. I started this role with no prior knowledge but was able to quickly achieve the necessary technical knowledge. Most of my time was spent in data analysis to monitor the tool health as well as developing new methods to extract data and analyze it to better track our tool health and the quality of our product. As tool issues arise, I collaborated with vendor experts to understand the issue, develop next steps and ensure a quick resolution. I had the privilege to be part of a relatively new team that comprised roughly 10 people and was thus able to help shape the development of this group through multiple high impact projects that improved our area productivity and minimized our quality risk. One of my most impactful projects was working with a team of 4 people to develop 30 + operating procedures for critical job duties, which increased our productivity and decreased our quality risk. Another impactful project that I worked with was the creation and implementation of a system to track the requalification of our scanners after repairs were completed. For this, 10+ requalification templates were created, as well as a system that will be used long term to track the time each re-qualification takes, and 20+ operational changes were made over the course of multiple quarters to reduce the time re-qualification takes.

As a Graduate Student Researcher, I worked in the lab of Mattanjah de Vries and specialized in using gas-phase laser spectroscopy (LD-JC-REMPI-TOF-MS) to study small molecules. I worked on multiple projects with other grad students studying nucleobases. Through our research, we hoped to understand the prebiotic selection factors in an early earth that would've caused the canonical bases to be chosen over structurally similar derivatives. We have postulated that the canonical bases have faster… Show more As a Graduate Student Researcher, I worked in the lab of Mattanjah de Vries and specialized in using gas-phase laser spectroscopy (LD-JC-REMPI-TOF-MS) to study small molecules. I worked on multiple projects with other grad students studying nucleobases. Through our research, we hoped to understand the prebiotic selection factors in an early earth that would've caused the canonical bases to be chosen over structurally similar derivatives. We have postulated that the canonical bases have faster excited state decay times that make them more photochemically stable than their alternatives. In one study, we used the spectroscopy techniques of resonance enhanced multiphoton ionization, pump-probe, and double resonance spectroscopy to probe the dynamics of the excited state of 2,4 diaminopurine. The project that I am proudest of used our technique as an analytical method to quantify theobromine, theophylline, and caffeine in Mayan pottery samples. I conducted all sample analysis and analytical method development for this project done in conjunction with Dr. Anabel Ford who provided the archeological analysis of the analytical results. While organic residue analysis is a well developed field of study, our instrumentation was a completely new analytical technique and required much method validation. I was able to validate that our instrumentation provided better separation and a 10x improved LOD. Show less

I worked first as a mass spec facility assistant for ~3 months. Then I worked part-time as the Mass Spec Facility Manager for ~6 months to keep the chemistry department mass spectrometry facility operational until a new full time manager could be hired. During this position I was in charge of all maintenance and upkeep of a Bruker MADLI-TOF-MS, a Waters ESI-LCT-TOF-MS, and a Waters GCT Premier TOF-MS. Most of the job entailed running faculty and student submitted samples including peptides… Show more I worked first as a mass spec facility assistant for ~3 months.

As part of the Mickey Leland Energy Fellowship, I interned with the Department of Energy to compile and analyze the previously collected coal quality data to study regional differences in coal ranks. I also designed a model business plan for a potential power plant.

· Daily duties involved the scientific collection, testing, and quality control of manufacturing products·Performed procedures crucial to quality controls, including pH testing, instrument calibration, titration, filtration test, and bleach test. ·Prepared accurate lab reports, sample logs, and certificates of analysis·Followed EPA and OSHA mandates to ensure the proper, safe disposal of hazardous samples and waste and maintained a safe work environment consistently.

I worked in the lab of Dr. Linda De la Garza working on studying the surface states of iron oxide photoanodes. I created the photoanodes using thin film deposition and analyzed these states through spectroelectrochemical characterization methods including chronoamperometry and photoinduced electron transfer.
