I work in the field of stellar astronomy. My research is largely observational in nature and based on X-ray, ultraviolet, optical, and infrared observations from space-based and ground-based observatories. I am interested in understanding how the magnetic activities on low-mass stars change with time as well as with the evolutionary stages. I am interested in studying the spot-topographic evolutions on the stellar surface, the surface differential rotations, the post-flare coronal loop oscillations, the flaring activities on the stars, and the exoplanetary systems if exist. These investigations on the stellar environments provide very useful constrains to the stellar magnetic dynamo theory. This also helps to understand the planetary habitability conditions in stellar environments. Apart from this, my interests also extend to studying the stellar wind properties of single and binary massive stellar systems, X-ray binaries, and X-ray transients as well as evolved stellar systems.

I am currently affiliated in Monterey Institute for Research in Astronomy (MIRA). This is a non-profit astronomical observatory founded in 1972 and dedicated to research and education in astronomy. It is the first independent professional observatory founded in the 20th century.
The Institute operates the Oliver Observing Station atop 5000-foot Chews Ridge. The station houses a 36-inch reflecting telescope used for astronomical research. Because of the excellent atmospheric conditions in the Santa Lucia Mountains, the first to intercept the smooth airflow from the Pacific Ocean, and the dark skies of the Los Padres National Forest, the observing conditions are among the best measured in the world. MIRA selected the Chews Ridge site because of its excellent conditions for optical astronomy. The median seeing at the site is 0.9 arc seconds over the entire year.
The figure on the right-hand side shows the front page of the MIRA Newsletter (Summer 2021 issue), featuring two astronomers (Daniel and me) in front of our telescope at Oliver Observing station.
