Early life and education

edit

Klausen is from Brookline, Massachusetts. She was an undergraduate student in biochemistry at Boston College. She moved to Harvard University as a graduate student, where she worked under the supervision of Eric Jacobsen and studied asymmetric Pictet–Spengler reactions.[1][2][3] She moved to New York for postdoctoral research, joining the lab of Colin Nuckolls at Columbia University.[1] There, she studied the conductive properties of molecules containing a 1-D chain of silicon atoms,[4] as well as other fluorene-derivatives that can act as molecular wires.[5]

Research and career

edit

Klausen began her independent career at Johns Hopkins University in 2013. Her research group studies organosilicon compounds, including poly(cyclosilane)s.[6][7] Klausen initially looked to create a bottom-up fabrication process for the realization of silicon-based materials, and to develop cyclo-silane building blocks for their polymerization.[8][9][10][11] Borrowing from the principles of carbon-based synthesis, Klausen has achieved precise control of the structure of silicon-based polymers.[8] She was named as the Second Decade Society Associate Professor in 2019.[citation needed] Klausen is part of the National Science Foundation Polymer Optimization Centre.[12][13]
