Graduate Research Associate

A 15 member research laboratory specializing in studying real-time physical chemistry and biochemical processes 

  • Collaborated in 2-4 person research teams conducting time-resolved and steady-state spectroscopy studies on biological systems to better understand fundamental scientific processes 
  • Completed a breadth of projects including studying local structural fluctuations of proteins and protein folding
  • Characterized protein dynamics through data analysis of femtosecond time-resolved spectroscopy data
  • Integrated all hardware for data acquisition and motion control using LabVIEW for femtosecond fluorescence spectroscopy up-conversion and transient absorption
  • Designed proteins optimally for time-resolved spectroscopy experiments, molecular cloning, cell expression and growth, and protein purification
  • Contributed to presentations at the annual International Symposium on Molecular Spectroscopy in Columbus, OH
  • Mentored new physics graduate students as they began their graduate studies at Ohio State
  • Designed and maintained Zhong group web page

Graduate Teaching Associate

A 15 member research laboratory specializing in studying real-time physical chemistry and biochemical processes 

  • Facilitator of introductory physics recitations, lab courses and tutor sessions as well as graded student homework, quizzes and exams (class sizes of ~20-35 students)
  • Participated in 5 to 10 member instructional team to coordinate teaching of lecture, labs and recitations 
  • Received teaching awards: American Association of Physics Teachers Outstanding Teaching Assistant Award and Hazel Brown Outstanding Teaching Assistant Award

Postdoctoral Researcher

The Ohio State University

Continued on projects from my graduate studies, resulting in a peer reviewed publication (currently in press).

Aug 2002 - Aug 2003

Contract Technician

Kodak Health Imaging

Pilot laboratory focusing on product development of Kodak's DryView brand of X-ray film

  • Entry-level chemical engineering position testing optical properties of X-ray largely for long term stability including photo-induced and thermal effects of film
  • Produced small batches of prototype X-ray film to improve quality and robustness of film
  • Presided over training of my replacement employees
  • Assisted with quality control at film production plant during production crisis
Sep 2001 - Aug 2002

Research Lab Assistant

University of Minnesota

Constructed detectors for high energy physics neutrino detection project MINOS at the scintillator and module factory

  • Partnered with students and staff to construct modules for MINOS with a focus on high quality production
  • Served as a student manager from June 2002-September 2002

Mathematica

LabView programming

Delevoped code for two different projects on two different versions of LabView 6 & 8.   The first project was simply a mimic of a setup that we had for each case.  For each project, additional hardware was interfaced with the program as well.
