“Tobi was a very rare type of person. … When you do a sabbatical many people in the lab ignore you, but Tobi ... without hesitation, said, ‘I’ll help you. Let’s go.’”

In this way, Tobias Walther’s simple question (“What are you working on?”) to Robert Farese Jr. started a long-term collaboration that has become the forefront research group in a new field of biology: how and why our cells make little droplets, called lipid droplets, and why that matters.

In the early 1990s, Farese had been studying enzymes that make oils. In his science, , Farese looks deeply at everyday things others pass over. Lipid droplets had been observed under microscopes since the 1800s, but Farese said, “When I went to the textbooks and tried to learn about them as organelles, I couldn’t find anything.”

Farese and Walther converged from complementary paths: one a U.S. lipid biologist with an M.D., the other a German chemist and biochemist who was a postdoc at the time. Additionally pooling structural biology, biophysics, proteomics, enzymology and physiology, over time they created excellent science.

“We stand on the shoulders of some amazing scientists,” Walther said, “but they didn’t have the tools that we have.”

For what they’ve done with these tools, Walther and Farese, now running a joint lab at Harvard University and both associate members of the Broad Institute, have won the 2022 偷拍偷窥 and 偷拍偷窥 Biology’s ASBMB–Merck Award.

Droplets by nature are isolated, but good science isn’t. For Walther, “It’s about the work and not (the two of us) … many people in our lab have contributed.” Farese attributes asking good questions to their “constant creative dialogue … ping ponging” ideas for experiments. Both buck egomania in science, appreciating a congratulatory note from mentors over a press release.

Feedback on the science itself, says Walther, is what shows “we’re on the right track.” That track increasingly has shown that there’s depth in a droplet, and there’s yet more to be found.
