(My website Equanimous Corner will be published soon …)

Areas of expertise

Developing instruments for ground-based telescopes (8-10 meters) to search and directly image (exo-)planets orbiting stars other than our sun. Below, you can find some public articles I wrote, describing a few research problems we are trying to solve:-


Areas of research interest

Extreme-Adaptive Optics mainly wavefront sensing and control, post-processing of exoplanet/debris disks and speckle suppression and control algorithms.


Current Affiliation (December 2022 - Present)

Adaptive Optics Associate Scientist
Gemini North Observatory
670 N A’ohoku Plave
Hilo 96720
Hawaii

I am the Project Scientist of the Gemini Planet Imager 2.0 instrument at Gemini North.


Fellowships and previous affiliations

I am incredibly grateful to the anonymous reviewers for recognizing my potential and giving me opportunities to perofrm my research work under the umbrella of these gracious titles.


Instruments I worked on

  • Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO), Subaru Telescope, Hawaii.
  • Palm-3K Extreme AO (P3K), Stellar Double Coronagraph (SDC) system and the high-contrast imager PHARO, Palomar Mountain, California.
  • Très Haute Dynamique 2 (THD2), LESIA, Observatoirde de Paris, France.
  • NEW EARTH Lab, Victoria BC, Canada
    My main project at NRC HAA includes developing a low-order wavefront sensor for CAL2.0 unit of Gemini Planet Imager (GPI 2.0) and merging the control loop with a focal plane wavefront sensor to improve exoplanet detection sensitivity at small angles. I am also developing an end-end simulation of an exoplanet imaging instrument for Thirty Meter Telescope.
