About Me

My name is Santosh Joshi, and I'm from the Syaldey block in Uttarakhand, India's Almora District. The mysteries of the universe have always captivated me, which is why I chose to study astronomy and astrophysics. My PhD and Master's degrees in Physics were awarded by Kumaun University in Nainital. Using photometric and spectroscopic methods, I studied the variability of chemically unusual stars for my doctoral thesis.

I am currently employed as a Scientist/Professor at the Aryabhatta Research Institute of Observational Sciences (ARIES), an autonomous institute under the Department of Science and Technology, Government of India.

My areas of interest in astrophysics study are broad and include:

• Asteroseismology
• Studies of chemically peculiar stars
• High-resolution spectroscopy and spectropolarimetry
• Census of variability in star clusters
• Constraining the orbit and determination of the basic parameters of binary stars
• Optical variability of Blazars
• Instrumentation initiatives (creation of rapid photometric systems for ARIES optical telescopes)

I investigate these areas using both spectroscopic and photometric techniques. More than 100 research papers that I have contributed have been published in prestigious international publications.

Using ground- and space-based telescopes, I have discovered stellar pulsations in numerous chemically unusual stars, along with a heartbeat star. I'm also interested in using AI and machine learning methods to categorize variable stars and comprehend their characteristics.

I have been involved in many national, international bilateral, and multinational projects, including:

• The Nainital-Cape Survey project, funded by the governments of South Africa's NRF and India's DST
• The Belgo-Indian Network for Astronomy & Astrophysics initiative, funded by the governments of Belgium (BELSPO) and India (DST)
• The BRICS consortium's SAPTARISI project, supported by the governments of China, Russia, and India
• Time Resolved Photometric and Spectroscopic Study of the Chemically Peculiar Stars, supported by the Russian Foundation for Basic Research and the Department of Science, Government of Russia

I have a strong desire to mentor young researchers and impart my knowledge to them. I have mentored several PhD and project students as part of creating a cooperative atmosphere for study and creativity.
