Stellar Atmosphere Research in Optical and UV Spectra
Welcome to our Group Webpage!
Our research interest lies at the heart of one of the unsolved problems of astrophysics, the Coronal Heating Problem: how energy is transported to the outer atmosphere of the Sun (or any Sun-like star) without heating the surface but creating the million-degree corona and accelerating the solar wind. To understand the phenomenon, we study the upper photosphere, chromosphere and the transition region of the Sun by means of various optical and UV telescopes such as Inouye Solar Telescope (DKIST), Parker Solar Probe (PSP), Interface Region Imaging Spectrograph (IRIS) and Atmospheric Imaging Assembly (AIA) on board of Solar Dynamics Observatory (SDO).
​
Key aspects of our research:
​
- Identification of sources of acoustic waves and the subsequent mode conversion in Solar Atmosphere (DKIST)
​
- Magnetic Reconnection and Nanoflare Heating at the upper chromosphere and the transition region (IRIS, SDO)
​
- Competitive Ion dynamics leading to turbulence in partially ionized plasma (IRIS, SDO, DKIST)
​
- Magnetic reconnection at the interface between coronal holes and loops, the so-called interchange reconnection, and its contribution to the formation of the highly variable slow solar wind (PSP, SDO)
​
- Explainable AI: Glass box deep learning models to facilitate knowledge extraction from astronomical observation (DKIST, PSP)
​
To bolster these efforts, we are are building an international collaboration to develop state-of-the-art solutions to above problems which we believe will open many new avenues in observational astrophysics.

About Me
I am Shah Mohammad Bahauddin, an early career scientist and astrophysicist. I am a research faculty, currently appointed at the Laboratory for Atmospheric and Space Physics (LASP). This facility operates under the umbrella of the Astrophysical and Planetary Sciences department at University of Colorado Boulder. I joined LASP right after I received my Doctorate in Physics from Rice University under the supervision of Prof. Stephen J Bradshaw. Prior to this, I completed two masters, one in Physics and one in Electrical Engineering, from Rice. Before coming to Rice, I earned my bachelor in Electrical and Electronics Engineering from University of Dhaka, Bangladesh.
​
I am a dreamer and an optimist. I believe in a world where knowledge and technology is democratized and accessed by all walks of life. I believe in conservation of nature and environment, not only because I believe it is the right thing to do, but because I want to leave a sustainable future for my children and their children.
DKIST Ambassadorship
The Daniel K. Inouye Solar Telescope (DKIST, formerly the Advanced Technology Solar Telescope, ATST) represents a collaboration of 22 institutions, reflecting a broad segment of the solar physics community. In 2019, I was selected a DKIST ambassador. The DKIST Ambassador program provides financial support for graduate students and/or early career scientists at US universities for up to two years. The research conducted by the DKIST Ambassadors during this
time has strong links to DKIST Critical Science planning efforts and focus on the development and implementation of early Science Use Cases. The overall goal of the DKIST Ambassador program is to create a well-networked cohort of DKIST Data experts at US Universities who can support and participate in the creation of Level 2 data products for DKIST through the implementation of DKIST Science Use Cases.
