The examination format usually adopted in the astronomy program is for the student to present the results of his/her research in the form of a colloquium address lasting 45-60 minutes. The chair then invites members of the audience to ask general questions about the candidate's talk for a few minutes. The audience is then invited to either leave, or to stay and witness the detailed examination of the candidate by the committee. Finally the committee meets in executive session to decide whether the candidate has passed the examination and, if so, what modifications are required before the dissertation be accepted.
I will also present results from other studies on the pre-main sequence population of young clusters, concerning the problem of estimating ages and age spreads, in order to asses is star formation is a fast or slow process; the evolution of the spatial structure in young clusters, as well as the measurement of disk mass-accretion rates, and their decay
over time during the first few Myr of evolution. Last, I will introduce a few projects I will be working on during my new appointment at UVa. These include the on-going extension of the IN-SYNC survey in the entire Orion star formation complex, to study stellar properties and kinematics in a large (>100pc) region. I will use new HST data to analyze stellar properties and mass accretion rates in a young protoclusters, as well as HST data to derive the complete substellar IMF down to planetary masses in the Orion B star forming region.
