Document:
I am a fourth-year PhD candidate in the Chmielus Lab at the University of Pittsburgh (Pitt) in Materials Science and Engineering. I completed my Bachelor's degree at Pitt in 2015, also earning a degree through the University Honors College requiring a Master's-level thesis. My long-term career goals are focused on microscopy in materials science and lab management.
My topic experience includes additive manufacturing of metals and multifunctional materials, particularly Ni-Mn-based magnetic shape memory alloys and magnetocaloric materials.
Microscopy is my passion. I am most familiar with digital optical microscopy, scanning electron microscopy (including energy-dispersive x-ray spectroscopy and electron backscatter diffraction), and micro-computed tomography; but I have also used transmission electron microscopy, differential interference contrast microscopy, and atomic force microscopy.
The fusion of art and science that can be seen through a microscope is unparalleled by any I have ever experienced. Microscopy is a multi-faceted tool giving us the ability to probe previously unseen mysteries and share our findings through universally relatable images. Microscopy is also the reason my job is so much fun.
As President of EGSO, I worked with the VP to completely restructure the organization and increase the amount/quality of our events. My role in PittSWE is a consulting one currently, but I was VP my senior year. Toastmasters is a public speaking and leadership organization. I have been in the Oakland Toastmasters club since the 2012, and served as club VP Public Relations and President in addition to my current role as Area 34 Director. In August, I will transition to President of the Microscopy Society of America Student Council, coordinating a board of officers from all over the nation (and a few internationally) to conduct programming for student MSA members throughout the year as well as a pre-meeting congress for student, post-docs, and young career professionals at the Microscopy & Microanalysis annual meeting.
