Mark Christopher Hersam (born January 31, 1975) is a professor of Chemistry and Materials Science Engineering at Northwestern University (2000–present) who, according to the National Science Foundation, has made "major breakthrough[s]" [1] in the field of nanotechnology. He is a 2014 recipient of the MacArthur "Genius" Award and a 1996 Marshall Scholar.[2] He is also an Executive Editor of ACS Nano. As of October 2023, he has been cited over 68,000 times according to Google Scholar.[3]

Education and early academic work[edit]


Mark Christopher Hersam[4] attended Downers Grove South High School in Downers Grove, IL where he was Valedictorian[5] and an Eagle Scout. He then went on to receive his B.S. in Electrical Engineering at the University of Illinois at Urbana-Champaign in 1996. Upon winning the Marshall Scholarship,[6] Hersam received a M.Phil. in Microelectronic Engineering and Semiconductor Physics from the University of Cambridge in 1997. His Ph.D was granted from the Electrical Engineering Department at the University of Illinois at Urbana-Champaign in 2000.[4]

Early work[edit]

While at UIUC, Hersam did research[7] under Professor David Ruzic[8] in the Nuclear Engineering Department and Professor Joseph Lyding[9] in the Electrical Engineering Department.

After graduating from UIUC, Hersam was an intern at the Argonne National Laboratory where he did research in the Energy Technology Division studying the energy-related applications of surface acoustic-wave-based sensing.

While at Cambridge University, Hersam was advised by Mark Welland and the two co-authored the paper "Potentiometry and repair of electrically stressed nanowires using atomic force microscopy"[10] in the journal of Applied Physics Letters.

As a doctoral candidate, Hersam again worked with Professor Joseph Lyding at the Beckman Institute where they studied "atomic level manipulation and silicon-based molecular nanotechnology."[11]


As head of the Hersam Group at Northwestern University,[12] Hersam has authored more than 137 peer-reviewed publications[13] studying hybrid hard and soft nanoscale materials[14] for applications in information technology, biotechnology, nanotechnology, and alternative energy.
