However, I soon added Gravity Spy (LIGO) and Supernova Hunters (TNS-IAU) to my list of interests. Out of all these, I began working on Disk Detective in 2014 and worked mainly with that project from then on. It used astronomical resources and databases that were much like the ones I used in my astronomy hobby growing up. The Disk Detective team was also the most engaging of any project I participated in, and it incited me to want to do more with them. I was also asked to help with certain physics problems involving several disk candidates.</p></div></div></div></div><div class="BlockLayout BlockLayoutPeople grid-row grid-container grid-container-block padding-x-0 margin-y-3"><div class="grid-col-12"><div class="BlockWrapper hds-module width-full maxw-full CoreParagraphBlock"><div class="grid-container-block grid-container padding-0"><p class="margin-0 padding-0">One thing I really appreciate in volunteering for NASA is that I've never felt pressured to do more than I've been capable of.

part of my life. I was pleasantly surprised when Dr. Kuchner came across samples of my work and asked if I could depict one of our discoveries for a NASA press release. I was honored to contribute what I could, using data gathered by both our Disk Detective team and, when NASA's Jet Propulsion Laboratory (JPL) asked for an updated image, Simon Murphy's team (who made valuable supplemental discoveries). The JPL artwork also caught the notice of the University of Michigan's Museum of Natural History, which approached us for permission to use it in an exhibit. So I am pleased that what we're doing with Disk Detective is now being used to educate the public about the solar system and planet formation.</p></div></div></div></div><div class="BlockLayout BlockLayoutPeople grid-row grid-container grid-container-block padding-x-0 margin-top-5 margin-bottom-2"><div class="grid-col-12"><div id="hds-sidebar-nav-5" class="BlockWrapper hds-module width-full maxw-full CoreHeadingBlock"><div class="grid-container-block grid-container padding-0"><h3><span>What have you discovered or learned as a NASA citizen scientist?</span></h3></div></div></div></div><div class="BlockLayout BlockLayoutPeople grid-row grid-container grid-container-block padding-x-0 margin-y-3"><div class="grid-col-12"><div class="BlockWrapper hds-module width-full maxw-full CoreParagraphBlock"><div class="grid-container-block grid-container padding-0"><p class="margin-0 padding-0">It's been a privilege learning to be part of a great team making discoveries that are questioning what we know about the science of the solar system and planetary formation, such as the newly classified Peter Pan disks.

So, I've been learning how to help build a website that will collect data from millions of citizen scientists worldwide.

My grandparents also nurtured my love for science and gifted me my own subscription to National Geographic.
