Biogharphy:

Donhee Ham is Gordon McKay Professor of Applied Physics and EE at Harvard University, where he has been since September 2002.

Ham, from Busan, Korea, earned a B.S. degree in physics from Seoul National University in 1996, where he graduated summa cum laude with the Presidential Prize, ranked top 1st across the College of Natural Sciences, and also with the Physics Gold Medal. Following a 1.5-year military service in the Korea Army, he went to Caltech for graduate training in physics. There he worked on general relativity and gravitational astrophysics under Professor Barry Barish while in physics, and later obtained a Ph.D. in EE in 2002 winning the Charles Wilts Prize awarded for the best thesis in EE. His doctoral work examined the statistical physics of electrical circuits. He was the recipient of the IBM Doctoral Fellowship, Li Ming Scholarship, IBM Faculty Partnership Award, IBM Research Design Challenge Award, and the fellow of the Korea Foundation of Advanced Studies. He shared Harvard's Hoopes prize with William F. Andress. He was recognized by MIT Technology Review as among the world's top 35 young innovators in 2008 (TR35). Ham was selected as a Harvard Yearbook Favorite Professor 4 years in a row (2011-2014), and was one of 8 Harvard Thinks Big speakers in 2012 (8 Harvard faculty chosen by college-wide votes). He served as an IEEE Distinguished Lecturer for the Solid-State Circuits Society (2012-2013).

Ham's work experiences include Caltech-MIT LIGO, IBM T. J. Watson Research, Consulting Visiting Professorship at POSTECH, Distinguished Visiting Professorship at Seoul National University, IEEE conference technical program committees including the IEEE ISSCC and the IEEE ASSCC, advisory board for the IEEE ISCAS, and various US, Korea, and Japan industry, government, & academic technical advisory positions. He served as a guest editor for the IEEE Journal of Solid-State Circuits and was a co-editor of CMOS Biotechnology with Springer (2007).

He is an associate editor for IEEE Transactions on Biomedical Circuits and Systems.

 

Abstracts: 

From Flatland Electrodynamics to Molecular Spectroscope and Neurotechnology with Solid-State Chips

We develop new solid-state materials and systems for applications in a range of scientific and technological problems encompassing EE, physics, and biology. This talk will highlight these efforts with select recent works. (1) Dimensionality profoundly influences condensed-matter electron behaviors, with 2D conductors––e.g., semiconductor quantum wells, graphene, and transition metal dichalcogenides––enabling discoveries of intriguing fundamental phenomena. One great effect of this reduced dimensionality concerns ultraslow plasmons. We obtained 2D plasmons 700× slower than free-space light. These ultraslow plasmons open up new exciting vistas for solid-state terahertz technology by enabling ultra-subwavelength light manipulation, strong light-matter interaction, and bandgap-less gain. I will present a host of 2D plasmonic circuits that compact and manipulate light in a broad variety of ways, and discuss fundamental 2D plasmonics experiments to measure the mass of massless graphene electrons and to obtain bandgapless terahertz gain via hydrodynamic energy transfer from direct current to ultraslow plasmons. (2) NMR spectroscopy that can elucidate structure and function of biomolecules at atomic resolution is a paramount analytical tool in biology and medicine and has proven enormously fruitful in pharmaceutical screening, structural biology, and metabolomics. But it suffers critically from inherently low throughput. I will share our program to develop a massively parallel––thus ultrahigh throughput––biomolecular NMR paradigm by exploiting silicon chip technology, and its applications in structural biology, drug discovery, and metabolomics. (3) Another biotech work is to create, in collaboration with Prof. Hongkun Park, CMOS-assisted vertical nanowire arrays as a new neurotechnology tool that parallelizes intracellular access into neurons. Experimentations with this unprecedented nano-bio interface will be discussed together with its applications in neurobiology, implanted technology, and brain machine interface.
