If you’ve ever been outside, you’ve probably noticed that some tree trunks and plant roots have weird looking tumor-like growths. In this video, I explain what causes these tumors, and how scientists have borrowed techniques from this natural process to add genes to plants. It is an educational video that cuts through the “are GMOs good or bad” debate to simply explain how they’re actually made. Hint: there are no syringes.

Have you ever wondered where farmers get their seeds? Don’t they just save and reuse seeds from the previous crop? This video explains what “hybrid” seeds are and the genetic basis for why farmers buy hybrid seeds year after year instead of harvesting the seeds from a hybrid crop and replanting them.

My research at UC Davis focuses on sequences once thought to be “junk DNA”, in this video, I describe my thesis in 3 minutes for an audience of museum-goers at the 2017 Science Talk Northwest conference in Portland.

As mentioned in the video above, introns can play surprising roles in gene expression. The effects of introns include increasing mRNA accumulation, changing spatial expression, and altering the location of the transcription start site, even in the absence of a proximal promoter sequences. This video provides a brief summary of much of the results from my dissertation research as presented at the 2016 Plant Genome Engineering Symposium at UC Berkley.
