This sudoku-inspired letter puzzle hides the name of an interdisciplinary researcher

Solve this wordoku in the same way as a sudoku with letters instead of numbers (each of the nine letters in each row, column and nine-square cell). Once solved, one of the overall diagonals can be rearranged to give the surname of a US-based interdisciplinary chemist with special interest in the bioinorganic chemistry of cancer.
