Karen Hughes has been a Lab Admin Coordinator with Scripps Research for over eight years. Most of her responsibility is to support the lab by completing the administrative work on grant applications, order supplies and equipment when tasked and to provide any other necessary support to the lab. Her background has been working in government and commercial settings providing support in the creation of grant submissions for over thirty years. She also has a hazmat background providing support by maintaining a database used to classify hazardous products based on the specifications stated in the material safety data sheets (MSDS). Karen brings her beloved 10 year old miniature dachshund office mate, Cooper, to work with her everyday and he makes sure that no one interrupts her work flow. When Karen isn’t at work she is generally found out on a hiking trail or clogging with her fellow dance friends.

Make no mistake about it. Karen runs the show. Anything you need, she gets it done… provided you can get by Cooper.

My name is Sam, so Sam I am, and I’m in the Grotjahn and Wiseman fam. I’m from the Alamo, so all you know, I came to Scripps to learn and grow. Mitochondria are key, for you and me, and I love to mess with them and see. Sometimes they’re long, sometimes they’re stout, and sometimes they’re angry and just kind of shout. It’s my hope, with my trusty ‘scope, to map these changes as mitochondria cope. The pictures are gorgeous, and sometimes glorious, and I’ll continue to take them until I’m victorious. Give me some time, and you will find, the continued development of my mind. I’m excited to be here, but I’ll never show it, but if you talk with me, you’ll most certainly know it. - bio in the style of Dr. Seuss, as per request.

I tell ya, folks, I’m in the academic rat race, but I get no respect! I’m over here, trying to unravel the mysteries of proteins like they’re some kind of cosmic puzzle, and all I get is blank stares and mutterings of ‘good luck with that’ from my peers. Growing up, I was all about the X-Men, you know? Mutations, superpowers, the whole shebang! So, naturally, I figured genetics and biotech were my bag. Went through high school and undergrad in India, soaking up everything I could about DNA and biotechnology like a sponge in a lab coat. Then, I land myself in Pennsylvania State University, diving headfirst into a Professional Masters program in Biotechnology. And let me tell ya, that was my first real taste of the big leagues. Drug discovery, biotech industry… it was like swimming with sharks in a sea of pipettes. After I graduated, I hightailed it to San Francisco faster than you can say ‘PCR’. Worked at this startup, tinkering away with proteins like SARM1, trying to figure out how they’re making axons go haywire in neurological disorders. Hit-to-lead campaigns, driving drugs to the clinic… it was like playing biochemistry chess with a side of lab-coated swagger! But hey, I ain’t done yet! Now, I’m back in the academic trenches at Scripps Research, ready to bridge the gap between academia and industry. Structural biology, biochemistry, you name it – I’m on a mission to answer the big questions, the ones that could maybe, just maybe, change lives down the road. When I’m not sciencing it up in the lab, you’ll find me kickin’ back at the movies, catching waves by the beach, or chowing down on some of the meanest baja fish tacos this side of the border. Hey, even a protein sleuth needs to refuel, am I right? - bio in the style of ‘Rodney Dangerfield’.
