Understanding the evolution of galaxies and the history of our universe is one of the most challenging questions in modern cosmology. One of the most important aspects of understanding the evolution of galaxies is measuring the rate of formation of stars (i.e., the star formation rate) and attenuation of dust content produced by massive stars in interstellar medium.

Currently, I am working with Dr. Naveen Reddy, studying star formation rate and dust attenuation of galaxies in the redshift range 1.5 ≤ z ≤ 3.5, when the universe was just ~ 3 Gyr old. This redshift range contains the peak of star formation in the universe and marks an important era in the history of the universe. We have a large sample of spectroscopically confirmed galaxies with multi-wavelength data, such as photometric H-alpha luminosities obtained by Keck telescopes, UV luminosities from Hubble Space Telescope, and mid to far infra-red observations from Spitzer and Herschel telescopes. I am planning to enhance my work by using rest-frame optical spectroscopic observations by MOSFIRE, the new near infra-red spectrograph on Keck I telescope, in near future.
