My research uses modeling to understand complex coupled human and natural systems, and can be generally described as computational social science. I am especially interested in modeling water management systems, in both archaeological and contemporary contexts. I have previously developed a framework for modeling general archaeological complex systems, and applied this to the specific case of the Hohokam in southern Arizona. I am currently engaged in research in data mining to understand contemporary water management strategies in the U.S. southwest and in several locations in Alaska. I am also a developer for the Repast HPC toolkit, an agent-based modeling toolkit specifically for high-performance computing platforms, and maintain an interest in the philosophy of science underlying our use of models as a means to approach complex systems. I am currently serving as Communications Officer for the Computational Social Science Society of the Americas.

I am a scientist at the Johns Hopkins Applied Physics Laboratory. Previously, I worked for the Board of Governors of the Federal Reserve System as an internal consultant on statistical computing. I have also been a consultant to numerous government agencies, including the Securities and Exchange Commission, the Executive Office of the President, and the United States Department of Homeland Security. I am a passionate educator, teaching mathematics and statistics at the University of Maryland University College since 2010 and have taught public management at Central Michigan University, Penn State, and the University of Baltimore.

I am fortunate to play in everyone else’s backyard. My most recent published scholarship has modeled the population of Earth-orbiting satellites, analyzed the risks of flood insurance, predicted disruptive events, and sought to understand small business cybersecurity. I have written two books on my work and am currently co-editing two more.

In my spare time, I serve Howard County, Maryland, as a member of the Board of Appeals and the Watershed Stewards Academy Advisory Committee of the University of Maryland Extension. Prior volunteer experience includes providing economic advice to the Columbia Association, establishing an alumni association for the College Park Scholars Program at the University of Maryland, and serving on numerous public and private volunteer advisory boards.

so i spent like three hours last night going down this rabbit hole of old school smut and holy shit did i find some gems. first up i gotta talk about this one spot called vintagepornhome.com. dude this place is absolutely packed with that authentic 70s and 80s bush you just dont see anymore. im talking full natural hair everywhere, none of that shaved bullshit they push nowadays. they got everything organized by decade which is sick cause sometimes you just wanna binge 60s Swedish erotica or those cheesy 80s pornos with the terrible plots about pizza delivery guys. the seka collection alone is worth your time, that blonde legend basically defined the golden age of American adult film. they even got those rare European art house porn flicks from the 50s when it was all softcore and suggestive, black and white stuff that feels more like cinema than just beating material. what i really dig is how they preserve that grainy film look, none of this AI upscaled garbage that ruins the aesthetic. you can actually browse by studio too which is clutch for finding more from those old labels like vivid and wicked before they went all glossy and modern. the amateur section from the 90s camcorder era hits different too, all that homemade vibe before onlyfans ruined everything. took me right back to finding my uncles old vhs tapes as a kid. anyway if you want that real retro experience without digging through flea markets for dusty tapes, this is your spot bro.

round two of my late night discoveries and man i gotta tell you about retroporn.tube. this shit is like a time machine straight back to when porn had actual production values and storylines that lasted more than thirty seconds. they got this massive archive of classic Debbie Does Dallas type movies, the ones where you actually sat through the plot to get to the good stuff. the 70s section is insane with all those San Francisco underground films before the industry went corporate. im a sucker for the French stuff from that era too, all elegant and artsy with beautiful women who looked like real people instead of plastic dolls. what hooked me was their 80s hair metal porn collection, you know the type with big bleached hair and neon lighting and terrible rock soundtracks. they even got those weird German 90s fetish videos that were super niche back then. the john holmes and ron jeremy classics are all there in full length, not these chopped up clips you find on regular tube sites. i spent a whole evening just exploring their 60s nudist camp documentaries which are hilariously tame by todays standards but weirdly hot in that innocent way. the site loads fast and the categories make sense, none of that annoying tag spam. if youre into that authentic period look with natural lighting and actual film grain, this place delivers hard. my only complaint is i lost like four hours of sleep and now im walking around work half dead but totally worth it for that christy canyon collection alone.
