He graduated summa cum laude with a doctorate in theoretical chemistry from the University of Tübingen, Germany, about linear-scaling electronic structure theory approaches for expedited and accurate predictions on large molecules. During his post-doctoral research at the University of California, Berkeley, Lambrecht developed new resolution of the identity approaches and worked on computational characterization of nanosolvation. He has 38 publications that have been cited more than 2,300 times, and his publication H- and i10-index are 19 and 27, respectively.
