About Me




Algorithm Developer, SolidCAM
  • Researched and developed toolpath generation algorithms for CAM software.
  • Experimented and collected data to guide algorithm development.
  • Developed algorithms needed for direct toolpath editing by the user.
Graduate Research Assistant, National Superconducting Cyclotron Laboratory
  • Set up and conducted a radioactive beam experiment to measure the 34Ar(α,p)37K cross section, using JENSA gas jet target and SuperORRUBA silicon detector array. The experiment is relevant for the understanding of X-ray bursts, and analyzed the data.
  • Designed and build a detector holding and positioning system.
  • Assembled the JENSA gas jet target and commissioned it using the 4He(p,p)4He and 14N(α,p)17O reactions.
  • Set up ASICs data acquisition for JENSA and ANASEN experiments in NSCL's ReA3 hall.
Undergraduate Research Assistant, National Superconducting Cyclotron Laboratory
  • Developed a micro-channel plate detector based beam intensity detector.
  • Worked on the development of the Active Target Time Projection Chamber.
Undergraduate Research Assistant, University of Notre Dame
  • Worked on stable beam experiments to study the 12C(12C,n)23Mg reaction, using the FN Tandem Van de Graaff accelerator.
