Meet the PUFFIN Team

The PUFFIN team work out of the Plasma Science and Fusion Center here at MIT, though we are from a range of departments. There are two graduate students, though we often have openings for undergraduates to join us for a UROP project. See the “Work With Us” page for more information about becoming part of our team!

Prof. Jack Hare (he/him, ) is an assistant professor in the Department of Nuclear Science and Engineering. His doctoral research was on magnetic reconnection driven by pulsed-power, carried out at the MAGPIE facility at Imperial College London. As well as magnetized high-energy-density plasmas, Jack enjoys hiking, cycling, climbing and caving. His personal webpage is

Rishabh Datta (he/him, ) is a graduate student in the Department of Mechanical Engineering at MIT. Rishabh is interested in magnetohydrodynamic turbulence in plasmas. In addition, Rishabh has a strong interest in sustainability and biodiversity conservation. Rishabh’s website is

Thomas Varnish (he/him, ) is a graduate student in the Department of Nuclear Science and Engineering at MIT. He is interested in using pulsed-power experiments to better understand astrophysical plasmas. Outside of the lab, Thomas enjoys baking, knitting, and the odd bit of snowboarding. His website is

Simran Chowdhry (she/her, ) is a graduate student in the Department of Nuclear Science and Engineering at MIT, jointly working with Jack Hare and Nuno Loureiro. She is interested in radiative effects and instabilities in magnetic reconnection. Outside work, she enjoys playing the cello, singing and rowing.

UROP Students

We actively recruit UROP students to run research projects within the group. If you are interested in registering for a UROP project with us, visit the “Work With Us” page.

Prof. Hare is co-PI of the MARZ collaboration (Magnetically Ablated Reconnection on Z), a Z Fundamental Science collaboration to run magnetic reconnection experiments on the Z machine at Sandia national labs. Z is the most powerful pulsed-power facility in the world, capable of delivering 25 MA current pulses. With MARZ, we will study strong radiative cooling in magnetic reconnection and the development of magnetized shocks. The MARZ collaboration includes Clayton Myers (SNL), Sergey Lebedev and Jerry Chittenden (Imperial College London), Dmitri Uzdensky (University of Colorado Boulder), Carolyn Kuranz (University of Michigan Ann Arbor), and Will Fox and Hantao Ji (PPPL).

We collaborate with Prof. Loureiro’s group at MIT, who carry out theoretical work on the connections between magnetic reconnection and magneto-hydrodynamic turbulence.

We work with the High Energy Density Physics group at MIT, who design state of the art diagnostics for two of the largest lasers in the world; OMEGA and NIF, as well as for Z, the world’s largest pulsed-power machine, at Sandia National labs.

We use the 3D MHD GORGON code, developed by Prof. Chittenden at Imperial College, to design and model our experiments.

We collaborate with researchers at other pulsed-power facilities across the US and internationally, including the COBRA generator at Cornell, the MAIZE generator at Ann Arbor, Michigan, and the MAGPIE generator at Imperial College London.


Of course, we wouldn’t be here without the puffins, some of the most charismatic birds on the planet. Ungainly in flight but unbelievably elegant in the water, puffins spend the winter at sea and the summer nesting on isolated cliffs. Puffins have only one chick per year, the puffling, and they feed it on sand-eels which they scoop up from the water and collect on special barbed spikes inside their beaks. Below are some photos of puffins taken by team members:
