Brad Dodrill

VP Applications/Senior Scientist

Because about 80% of our customers are physicists, materials scientists, and electrical engineers, it is important to them that we are able to demonstrate that we really understand their science, their applications, and their needs. We are very conscious that we are not just selling a product; we work with our customers in a collaborative capacity to ensure that we are providing them both the tools and services they need to advance their research endeavors.

Brad Dodrill graduated from The Ohio State University in 1982 with a BSc degree in Physics. He completed 2 years of graduate studies in Physics and Electrical Engineering and took a position with Lake Shore Cryotronics in 1984 as a Research Scientist. He was promoted to Systems Applications Engineer (1989 – 1996) and served a key role in the development of a commercial AC susceptometer/DC magnetometer and a vibrating sample magnetometer. He later served as an Applications Scientist and Product Manager (1996 – 2002), and in 2002 he was appointed VP of Sales.

In 2018 he transitioned to his current position as VP of Applications and Senior Scientist. He has co-edited a book (Magnetic Measurement Techniques for Materials Characterization), has 52 paper publications to his credit, and holds 3 U.S. patents. He has lectured at numerous universities and given invited and contributed talks at technical conferences in the U.S., Europe, Asia, and Mexico on vibrating sample magnetometry, AC susceptometry, alternating gradient magnetometry, and on the use of the first-order reversal curve (FORC) measurement and analysis technique for the characterization of magnetic materials.
