Research Interests

 
 

My primary research interests lie in particle cosmology: the intersection between the fundamental workings of the universe on its largest and smallest scales.  My work thus far has focused on two major questions at the cosmic frontier:


  1. What is the nature of the dark matter
    that drives the formation of large-scale
    structure in our universe?

        For details, see Dark Matter.




  1. What spurred the inflationary epoch that
    begins our narrative of cosmic history?

        For details, see CMB.





My efforts on both fronts involve the use of advanced detectors operated at sub-Kelvin temperatures to probe astrophysical signatures of new fundamental physics.



RECENT Work

My Ph.D. work was a search for particle dark matter with the Cryogenic Dark Matter Search (CDMS) collaboration. 


I currently lead the receiver team for SPIDER, a balloon-borne polarimeter which will search for the echoes of inflation in the cosmic microwave background.  I am also a member of the BICEP1/2/3 and Keck Array collaborations, which field a series of similar instruments at the South Pole.



EarlY Work

As an undergraduate I participated in two research projects in elementary particle physics.  I worked with Prof. Gary Feldman's group on MINOS, a long-baseline neutrino oscillation experiment at Fermilab and Soudan Mine. My main project was to work on software to describe the background flux of cosmic muons at the main detector in Soudan.  My senior research project was a study of proton decay using data from Super-Kamiokande under Dr. Mark Messier (Harvard) and Prof. Ed Kearns (B.U.). The mode I eventually chose to look at was K*(892) ν - sorry to report that no signal was seen.
