The Life of Ryan1
Ryan Kastner was born in Westmoreland County Hospital in Greensburg, PA — a city in the Allegheny Mountains and part of the Appalachian Mountain Range. He spent the first part of his life not to far from there playing with crayfish and other creatures in his backyard creek. He got an Atari 2600 for Christmas one year, and spent countless hours playing video games while eating iced animal crackers. In the rare moments that he wasn’t playing video games, he watched Scooby Doo, and ate iced animal crackers. To offset all of the animal cracker eating, he walked up a gigantic hill, in five feet of snow, both ways, every day, to West Point Elementary School. OK, maybe only one way, but it was a big hill.
Ryan moved to Medina, OH in fourth grade. He spent the next part of his life catching blue gill using cut up hot dogs in his backyard lake. Ohio is flat, so there were fortunately no hills to climb in going to Heritage Elementary School, Claggett Middle School, and Medina High School. However, there was five feet of snow at all times, even outside of winter; global warming has had a major effect on our climate. One year his parents bought him an NES which continued to fuel his love of video games. He woke up at 5:30am 6 days per week to deliver newspapers. This enabled him to buy more video games, newer gaming systems, and a bunch of worthless baseball cards that he still has (or rather his parent’s still have).
After many long years of waking up way too early, Ryan took a job as a dishwasher. This was his first “real” (tax paying) job. He quickly realized how great it was to be a paperboy. After four long months, he found a better job at the Waite and Sons Funeral Home. He performed gardening, cleaning, painting, car washing, and various other tasks around the funeral home. The fabulous Waite family showed him that hard work pays off. As he proved his worth, they gave him flexibility and respect. While he didn’t realize it at the time, this instilled a work ethic that made him successful throughout his life. He is forever indebted to them, particularly Ralph Waite, an unbelievable man and mentor.
All this work allowed him to graduate from video game systems to a desktop computer. He spent countless hours in high school upgrading his family’s home computers with parts from the local Walmart. Don’t ask about how he got those parts… The computer was often not functional, but when it was, it was fast and powerful. He also spent way too much time on the Medina County Library FreeNet service. This foretold his later addiction to the Internet.
After high school, Ryan started his gradual move westward across the country. He went to Northwestern University just north of Chicago to study engineering. It was far enough away from Ohio so that his parents could not just drop in unannounced, but close enough that he could have drive home so that Mom and Dad could do his laundry (and give him more money). Ryan’s parents spent way more money than they could afford putting Ryan through college. He will never be able to repay that debt.
Ryan started studying Chemical Engineering; this pursuit came to a quick halt when he got a C in chemistry freshman year. He then switched to Electrical Engineering. He mistakenly thought that majoring in something related to computers would make him hate his passion – building systems involving computers. Eventually he saw the light and double majored in Electrical Engineering and Computer Engineering. He continued to play video games throughout his college career. These were typically played in hazy, dark rooms with dear friends, some of whom went on to make video games. One of those friends was girl named Karen who introduced him to sushi and many other major life events (more on that later).
A defining life moment occurred during a VLSI CAD class with Prof. Majid Sarrafzadeh. For some reason, Dr. Sarrafzadeh thought highly of Ryan and offered him a research position. Ryan got paid and received class credit to work on interesting and open-ended problems on a crazy topic called reconfigurable computing. Pretty awesome! Several quarters of research convinced Ryan that academia was his calling, and he continued with Prof. Sarrafzadeh as a PhD student. All of his classmates thought he was crazy. Those classmates graduated and went on to make a lot of money during the dot com years while Ryan pulled in a bit above the poverty line as a graduate student.
In the year 2000, Prof. Sarrafzadeh decided to move to UCLA. Ryan decided to finish up his MS at Northwestern and moved to UCLA to do his PhD in Computer Science. Ryan had little money, no cell phone, and no car. He was probably the only person in LA at that time without a cell phone or a car. He did have an awesome cat name Dot who accompanied him to LA. Ryan and Dot will never forget the flight from Chicago to LA. Dot hated it because he was shoved in a carrier underneath the seat in front of Ryan. Dot expelled various bodily fluids in the carrier to let Ryan know how displeased he was with the situation. Ryan was similarly scared and excited (fortunately without emitting any bodily fluids), and will never forget looking out the plane window and seeing the lights underneath the smog of his new home.
Ryan spent the next two years doing research in high-level synthesis and reconfigurable computing. He wrote lots of technical papers, and spent hours playing board games at nights with his good friends in the Embedded and Reconfigurable Systems Lab. He spent every other weekend with Karen. He was grateful for her Saab, which allowed him to buy groceries, clothes, and other items not easily obtained using the Big Blue Bus. And it was pretty amazing spending time with her as well.
While he loved life at UCLA, Ryan decided that the pay was not ideal, so in 2002 he graduated taking only three years to do a combined MS and PhD. For some reason, he was a hot commodity on the academic market, and interviewed at 10+ universities around North America. He decided to stay in Southern California, taking a job as an assistant professor in the Department of Electrical and Computer Engineering at UC Santa Barbara. He bought a cell phone, obtained a car, rented a small place on the Mesa with an ocean view, and started his career as a young professor. He was so young that he was often mistaken for a student. Ryan misses those days…
Professor Kastner spent the next several years frantically starting up a research lab. He continued his research on reconfigurable computing. And he expanded into research topics related to hardware security and underwater sensor networks. The former got him a close friend and collaborator in Prof. Tim Sherwood. The latter got him a trip to Moorea in French Polynesia to test an underwater modem that he built with Prof. Hua Lee and Prof. Ron Iltis. This was when he caught a bug for applied research, especially projects that allowed him to travel. All this hard work paid off and Professor Kastner was given tenure at age 28, making him (perhaps?) youngest tenured professors in the UC system2. Another of his major accomplishments during that time was that he somehow convinced Karen to move to Santa Barbara without much of a prospect for a job.
In 2007, Karen grew tired of toiling as a post-doc at UCLA and trying to find a decent job around Santa Barbara. She went out and got professorial offers at many top bioengineering departments. Of those places, UC San Diego was the only place that could be suckered to also take in Professor Kastner as well. They moved to San Diego in 2007. Professor Kastner and Professor Christman also got married around that time.
Professor Kastner’s move to UCSD allowed him to further pursue his passion of applied research. He continued his work in hardware acceleration focusing on a wide range of applied problems including remote sensing, cell sorting, optical cardiac imaging, fast 3D object reconstruction, and high speed genome reconstruction. His hardware security work led to the formation of Tortuga Logic, Inc. And he continued his scholarly world travel as a founder and co-director of the Engineers for Exploration program. These pursuits have taken him and his students on expeditions to Maya archaeological sites in Guatemala, underwater shipwrecks in Lake Tahoe, and searching for the vaquita in Mexico.
