San Diego, California, United States

Work responsibilities include installing, maintaining, troubleshooting, repairing, and use of liquid chromatography (HPLC and UHPLC) instrumentation with a variety of detectors (UV, UV-VIS, fluorescence, refractive index, light scattering) and mass spectrometers (quadrupole, time-of-flight, and tandem). Duties require a high level of LC knowledge, self-sufficiency, organization, and integrity to meet internal and customer expectations. Knowledge and use of the Empower and MassLynx software packages are critical for daily activities.

Pasadena, California, United States

Projects included acting as Subtask Lead to continue R&D on the hypervelocity ice grain system (HIGS) involving both experimentation and modification to HIGS to investigate how impact velocity affects mass spectral distributions with an orthogonal TOF (oTOF); continuing role as Science System Engineer to develop, construct, and validate ion optics and a linear ion trap mass spectrometer brassboard for the Ocean Worlds Life Surveyor (OWLS) JNEXT project; developing techniques and methodologies to couple laser ablation to a Paul ion trap to obtain inorganic isotope identification and quantification for dating measurements (PDRDF #105275). Additional work centered on organizing and leading a 2-day workshop focusing on determining the ion optic needs of researchers at JPL, with ultimate implications for NASA in general. Experience also includes the preparation and submission of PICASSO and NIAC proposals (both as PI and Co-I).

Pasadena, Ca

Initial research projects focused on developing methods to ionize and detect low-vapor pressure organics of astrobiological significance using a miniaturized Paul trap developed at JPL; building and testing a new mini-Paul trap mass spectrometer system; and brining online, operating, and characterize a system that generates hypervelocity ice grains and molecules. Work for the OWLS JPLNext project included developing and constructing ion optics to interface electrospray ionization (ESI) and/or capillary electrophoresis (CE) sources to various mass spectrometers. Experience also includes the preparation, submission, and publication of scientific results; aiding in the preparation of DALI and PICASSO proposals; and being the mini-Paul trap POC for an Atelier study.

Stony Brook, Ny

Research focused on designing and building a custom instrument, which utilizes electrospray ionization (ESI), RF ion trapping (both ambient and cryogenic), time-of-flight (TOF) mass spectrometry, reflectron mass spectrometry, and laser spectroscopy. Reactive intermediates involved in atmospheric chemistry, heterogeneous catalysis, and gas-phase proteins were probed with IR action (CIVP) spectroscopy once the instrument is completed. Experience also included the preparation and submission of research grant proposals.Johnson Lab Website: https://sites.google.com/a/stonybrook.edu/johnsonlab/

Ventura, Ca

I was one of the Gordon Research Seminar (GRS) chairs for the very first Gaseous Ions: Structures, Energetics, & Reactions conference that was held in Ventura, CA on February 11-12, 2017. A GRS is a 1-day meeting held in conjunction with an associated Gordon Research Conference. The meeting is designed for graduate students and post-docs to present and exchange new data and ideas in a highly-stimulation and non-intimidating environment. The meeting also provides networking and professional development opportunities. My responsibilities as chair included organizing and leading the meeting, fundraising, allocation and distribution of funds, and ensuring the success of the seminar.I am pleased to announce that the GRS was a resounding success! 55 graduate students and postdocs from around the world attended the meeting which featured 11 oral presentations by young scientists, two poster sessions, a keynote address, and a career panel. I would like to thank sponsors for supporting the seminar -fundraising was so successful that all of the registration fees were able to be covered. I would also like to thank all of those who attended as well as our keynote speaker and panelists for helping to make the first ever Gaseous Ions GRS a meeting to remember.Gaseous Ions GRS Website: https://www.grc.org/programs.aspx?id=17457

Bloomington, Indiana Area

Research focused on elucidating the electronic and geometric structures of Group 5 and Group 6 transition metal oxides using the techniques of anion photoelectron spectroscopy and DFT calculations. Helped perform a resonant two-photon detachment experiment. Performed thorough reactivity studies on Group 5 and 6 transition metal oxides with methanol and ethanol.

Bloomington, Indiana Area

Aided in the teaching of the Graduate level spectroscopy course, Optical Molecular Spectroscopy (C566). Responsibilities included holding office hours and grading.

Bloomington, Indiana Area

Set-up and led undergraduate laboratory sections for Principles of Chemistry and Biochemistry (C117).

Indianapolis, Indiana Area

Aided in preparations and partial data analysis of an extensive study on the effects of asphalt materials and fumes on construction workers.

Indianapolis, Indiana Area

Early research used UV/VIS spectroscopic techniques to investigate aqueous iodine equilibrium reactions. Later research focused on determining properties of trapped hydrogen atoms in all-silicon zeolite cages using DFT.

Indianapolis, Indiana Area

Helped run various analytical tests on samples. Tests included determining total dissolved solids, partial dissolved solids, nitrates/nitriles content, and dissolved oxygen content. Additional content was determined utilizing GC-MS.
