CV Boot Camp 2024

About

Cyclic Voltammetry Boot Camp is a 3-day workshop designed to provide participants with the practical knowledge necessary to carry out robust cyclic voltammetry measurements in their independent research. The workshop includes both lectures and hands-on laboratory sessions.

Topics Covered
Coupled Chemical Reactions, Cyclic Voltammetry, Introduction to Electrochemistry, IR Compensation, Potentiostat Operation
Workshop Team
Alex Peroff, PhD
Pine Research Instrumentation
Electrochemical Sales Scientist

Alex Peroff joined the Pine Research team as an Electroanalytical Scientist in 2016. Alex came to Pine Research after earning his Ph.D. at Northwestern University under the direction of Richard Van Duyne and Eric Weitz. Following his doctorate, Alex completed a post-doctoral position at SUNY Albany. Alex resides in the Durham, North Carolina area.

Jillian Dempsey, PhD
University of North Carolina at Chapel Hill
Bowman and Gordon Gray Distinguished Term Professor

Jillian Lee Dempsey is an American inorganic chemist and the Bowman and Gordon Gray Distinguished Term Professor at the University of North Carolina at Chapel Hill. Currently, Research in the Dempsey group aims to address challenges associated with developing efficient solar energy conversion processes. We are particularly interested in charge transfer processes associated with solar fuel production, including proton-coupled electron transfer reactions and electron transfer across interfaces. Our research program bridges molecular and materials chemistry and relies heavily on methods of physical inorganic chemistry, including transient absorption spectroscopy and electrochemistry.

Megan Jackson, PhD
University of North Carolina at Chapel Hill
Assistant Professor

Megan began her scientific career as an undergraduate at Caltech. There, she conducted research in the laboratory of Prof. Harry Gray, where she was introduced to molecular synthesis, spectroscopy, and inorganic chemistry. This introduction to coordination chemistry and organometallics served as the lens through which she approached heterogeneous electrocatalysis as a National Defense Science and Engineering Graduate Fellow in the Surendranath lab at MIT. After receiving her Ph.D. in 2019, she joined the Long lab at UC Berkeley, supported by an Arnold O. Beckman Postdoctoral Fellowship and a University of California President’s Postdoctoral Fellowship Program Award. Her postdoctoral research focused on bringing molecular-level understanding to the factors governing the materials properties of metal-organic framework crystals. She joined the faculty at the University of North Carolina at Chapel Hill in 2022. Her favorite transition metal is Pt.

Li Sun, PhD
Pine Research Instrumentation
Senior Electrochemical Sales Scientist
Tim Paschkewitz, PhD
Pine Research Instrumentation
Principal Electrochemical Sales Scientist

Tim Paschkewitz, a true midwesterner originally from Wisconsin, has always had a passion for science, education, teaching, and people. Naturally, when Pine Research was hiring an electrochemist that would predominantly be involved in sales, Tim eagerly applied (after being encouraged by his graduate advisor that the position seemed as if written for him). After completing his Ph.D. in electrochemsitry at The University of Iowa in 2012, Tim began with Pine Research soon after. He naturally connects with people on both personal, everyday matters as well as on advanced electrochemical pathways. While not jet-setting around the world attending conferences and providing product demonstrations and training to customers, Tim manages the technical writing projects at Pine Research, including authoring many user guides, technical and application notes, and educational laboratory exercises. He also shares an important role in the marketing efforts of the company, in areas including social media, videos, print and digital media, advertising, and website management. Tim provides valuable insight to our engineering staff as to what new products and software features are needed in the electrochemical community. Recently, Tim has taken on the role of sales scientist for the new neuroelectrchemical product line. He accomplishes all this with the support of an amazing sales team…and a lot of coffee.

Kathleen Nevins, PhD
University of North Carolina at Chapel Hill
Director of Undergraduate Labs

Dr. Kathleen Nevins is the Director of Undergraduate Laboratories within the UNC Department of Chemistry. Kathleen earned her Ph.D. in inorganic materials chemistry from SUNY Buffalo under Dr. David Watson and began working at UNC directly after graduate school in 2013.
