I am a Simons Junior Research Fellow at Columbia University in the city of New York primarily exploring the Milky Way Galaxy (its formation, evolution and structure) using stellar spectroscopy as my tool.
My main interest is in using multi-object spectroscopic surveys to better understand the chemo-dynamic properties of the Milky Way (Galactic Archaeology). My expertise are in high- to low-resolution spectroscopy and stellar chemical abundance patterns. For a full CV click here
I completed my Ph.D. in 2016 at the Institute of Astronomy in Cambridge UK , under a Marshall Scholarship , and King’s College Cambridge Studentship. I primarily worked with Prof. Gerry Gilmore. I received my B.S. in Astrophysics (with minors in Mathematics and African Studies) from Ohio University in 2013.

Recent Talks / Workshops
My research program has been focused on developing an understanding of the formation and assembly of the Galactic halo using large surveys. One way to do this is study the different stellar population in the halo chemically and kinematically. Outside of my Ph.D. work I am interested in the following:
I am actively involved in outreach of many kinds at the Institute of Astronomy and have been involved in outreach efforts in various places around the world. I have helped organize and run ‘public observing’ and given a series of outreach talks to middle school, high school, undergraduate as well as the general public.
In the summer of 2013, I developed, coordinated and ran a 2-day workshop on ‘Demystifying the Science Fair‘ geared for middle/high school students in Athens, Ohio that was designed encourage them to compete at the highest levels of science competition for their age group.
Since coming to Cambridge, I have been active in public observing and most recently have giving a talk entitled “Galactic Archaeology and the Life of the Young Astronomer” to a group of Year 11 (15 year old) students that were a part of the Black, Asian, Minority, Ethnic (BAME) summer program at Cambridge.
I am extremely interested in and work towards encourage more students from underrepresent groups to participate in the sciences and in particular astronomy. So if you are working on projects to get more minorities involved in astronomy/science, I would love to hear your thoughts or help in anyway I can!
I am also the former chair of the King’s College Graduate Society (KCGS).
