Postdoctoral Fellows


Mark Nowakowski

Postdoctoral Researcher
nowakows AT berkeley DOT edu

Mark received his B.S. in Materials Science and Engineering from the University of Illinois, Urbana-Champaign in 2005 and his M.S. and Ph.D. degrees in Physics from the University of California, Santa Barbara in 2010 and 2011.

His research interests have focused on developing energy efficient magnetic technologies in a wide variety of materials, which include metals, semiconductors, ferromagnetic semiconductors, complex oxides, multiferroics, and suspended magnetic particles for applications such as quantum computation, memory, logic, sensing, and microfluidic particle manipulation. He has characterized these systems with optical, synchrotron x-ray, and transport-based measurements and has developed time-resolved optical and x-ray methods to study fundamental nanoscale magnetic properties on ultrafast timescales.


Jeongmin Hong

Postdoctoral Fellow
jehong AT berkeley DOT edu

Jeongmin Hong received his Ph.D. from the University of California, Riverside CA in 2009.

His research has focused on two areas: 1) developing the Spin Transfer Torque based logic devices using Magnetic Tunneling Junctions (STT-MTJs) and 2) investigating new functional magnetic materials for next generation advanced electronics and medical applications. More recently, he has been leading the development of sub-10-nm probe-based MTJs with extremely low switching energy. He is the author of over 30 journal papers (H-index: 8) and has 2 filed patents on the primary topic of Nanomagnetics, and also serves as an editorial board member in Nature Scientific Reports and PLoS One. He was a graduate researcher supported by NSF-MRSEC at the University of California, Riverside, CA, where he worked on magnetic and electric properties of carbon nano-structures and state-of-the-art technology of magnetic materials/devices in collaboration with hard disk drive companies.


Jon Gorchon

Postdoctoral Fellow
jgorchon AT lbl DOT gov

Jon received his engineering degree and M.A. in nanosciences in 2011 from the National Institute of Applied Sciences (INSA) of Toulouse, France. During his studies he completed an exchange year in Tohoku University in Sendai (Japan), where he initiated his lab training in the Information and Storage Systems group. He then worked as a PhD student on field and current induced magnetisation dynamics in metallic and semiconducting ferromagnets at the Laboratoire de Physique des Solides in Orsay (near Paris).

After he completed his PhD in 2014, he joined the Bokor group at UC Berkeley in order to study ultrafast magnetisation dynamics and spin-orbital effects by using an amplified femtosecond laser and different magnetic probing techniques such as MOKE or MSHG.


Richard Wilson

Postdoctoral Fellow
r.b.wilson AT berkeley DOT edu

Rich received his B.S. degree in mechanical engineering and applied physics from Utah State University in 2009 and earned his M.S. in physics in 2010. He earned his Ph.D in Materials Science and Engineering from the University of Illinois, Urbana-Champaign in 2015. At Illinois, his research focused on understanding conductive heat transfer at the nanoscale.

His current research is focused on developing a nuanced understanding of electronic, magnetic, and thermal transport phenomena in novel materials. He is currently studying the magnetization dynamics of ferromagnetic and ferrimagnetic metals on ultrafast time scales.


Kyunghoon Lee

Postdoctoral Fellow
leekhoon AT berkeley DOT edu

Kyunghoon received his B.S degree in electrical engineering and physics (with minor in mathematics) from Yonsei University (Korea) in 2004. He then completed his Ph.D in Electrical Engineering from the University of Michigan in 2015 after having industrial and research experience for four years at LG CNS and KIST. During his graduate years, he studied quantum transport in two-dimensional materials (such as Klein effect in bilayer graphene and MoS2 single electron transistor, etc).

He is interested in condensed matter physics from experimental perspective; quantum transport and novel nanophysics (quantum-spin-hall effect, spin and valley physics), quantum information processing with quantum dots, novel fabrication technique at nanometer scale, low-temperature measurement techniques, novel optoelectronic applications low-dimensional materials (quantum dot, nanowire, graphene, TMDCs, topological insulator/superconductor). Especially now, his focus is on about exploring into novel electronic behavior or new state of matter using GNRs.

Graduate Students


Yang Yang

5th year graduate student, MSE
y-yang AT berkeley DOT edu

Yang got his B.S. in mathematics and physics from Tsinghua University, China. Yang works on studying ultrafast spin dynamics with femtosecond laser. To investigate ultrafast spin dynamics triggered by ultrashort laser pulse (60fs), he built up a Time-Resolved Magneto Optic Kerr Effect (TRMOKE) setup. With this we are able to probe the spin dynamics within one picosecond.

He is working on projects such as heat assisted spin-hall switching and ultrafast all-optical switching of GdFeCo.


Akshay Pattabi

2nd year graduate student, EECS
akshaypattabi AT berkeley DOT edu

Akshay received his B.Tech. in Electronics and Communication Engineering from National Institute of Technology Karnataka, India in 2014.

His research interests include nanomagnetism and ultrafast magnetization dynamics, and he is currently working on a project on Spin Hall Effect. Spin Hall Effect is the creation of a spin imbalance transverse to the direction of charge flow in materials with high spin-orbit coupling. Potential applications of this phenomenon include integration into spintronic devices for memory and logic. The aim of the project is to measure Spin Hall Effect in different metals optically through magnetization induced second harmonic generation.


Juan Pablo "JP" Llinás

2nd year graduate student, EECS
jpllinas AT berkeley DOT edu

JP received his B.S. in Electrical Engineering from the University of Illinois, Urbana-Champaign in 2014.

JP investigates the electrical transport and optical properties of self-assembled graphene nanoribbons (GNRs) and GNR heterojunctions via device measurements and optical spectroscopy. His goal is to fabricate high performance GNR devices.
