For those who absolutely HATE taking attendance... but still have to. I built something for us. Request a FREE demo and see how it works. 📱 AttendanceAF.com ✅ Fast ✅ Simple ✅ No clipboards ✅ No spreadsheets ✅ No nonsense Because life's too short to spend 15 minutes figuring out who's actually in class. #AttendanceAF #HigherEd #EdTech #CollegeProfessor #FacultyLife #Teaching #HigherEducation #ProfLife

You ever notice how universities keep talking about "work-life balance" and then hand you enough classes to qualify as a small school district? This fall, I'll be teaching so many students that I’m pretty sure the registrar is just assigning freshmen to me by zip code now. At this point, if one more section gets added, I'm going to need air traffic control clearance before I walk into the classroom. But hey, after 23 years at ASU, I still love every minute of it. The students are awesome, the energy is contagious, and apparently my reward for surviving all these years is... even more students.

I Built a Doctor in a Box. It Runs Offline. It Could Save Lives in Africa. In 2003 I received an NIH grant to build a clinical decision engine that could produce a medical differential diagnosis‚ and replicate the reasoning of any individual physician. It worked. Twenty-three years later I picked the idea back up. This time with AI as my partner. The result is Occam Rx. The Problem A Peace Corps volunteer is stationed in a village in the Democratic Republic of Congo. No doctor within 80 kilometers. No internet. No electricity grid. A child arrives with high fever, shaking chills, and confusion. Malaria? Meningitis? Typhoid? The symptoms overlap. Guessing wrong is fatal. She has her training. She has her instincts. She does not have a tool built for this exact moment. Until now. What Occam Rx Does Occam Rx is a fully offline clinical decision support app built on four tables and one scoring engine. A volunteer walks a patient through 30 intake questions ‚Äî fever pattern, respiratory symptoms, neurological signs, skin changes, exposure history. Each answer fires weighted scores against 20 diseases endemic to central and eastern Africa. The five highest-scoring diseases surface as the differential diagnosis in real time. Not one answer. A ranked differential. Exactly how a good physician thinks. It runs on a $150 Android tablet. Charged by a $35 solar power bank. Zero internet required. What Makes It Different Five languages - English, Kiswahili, French, Amharic, Lingala Vital signs wired into the scoring engine‚ heart rate, temperature, SpO2, blood pressure, MUAC HIV status and pregnancy - both feed the differential automatically Field drug reference‚dosing by weight and age for all 20 diseases Patient records and analytics** ‚every intake saved anonymously on device Full patient chart, tap any record to see the complete clinical picture The 20 diseases: Malaria. TB. HIV/AIDS. Typhoid. Cholera. Dysentery. Pneumonia. Meningitis. Dengue. Yellow Fever. Schistosomiasis. Sleeping Sickness. Leishmaniasis. Measles. Malnutrition. Anemia. Hepatitis B. Tetanus. Rabies. Intestinal Parasites. Built With AI I want to be transparent. I built Occam Rx in collaboration with AI writing the scoring engine, populating medical content, translating five languages, designing the UI. This is what AI-assisted development looks like at its best. My clinical architecture expertise from 2003. Claude's medical knowledge and engineering capability. Neither of us could have built this alone. The Mission A Peace Corps worker in a remote village in central or eastern Africa, with no doctor, no internet, and a sick patient in front of them, picks up a small tablet and gets a clinically sound differential diagnosis with actionable field remedies in under 5 minutes.* Matthew J.

AttendanceAF is a full-stack attendance tracking platform built specifically for educators who are tired of wasting the first ten minutes of every class. Using rotating QR codes that refresh every 30 seconds, students check in instantly from their phones while professors watch the roster update in real time. Built by Professor Matt McCarthy, a 23-year veteran of Arizona State University's W.P. Carey School of Business who has taught more than 90,000 students, AttendanceAF solves a problem that no existing tool has solved at scale. The platform is FERPA compliant by design, not by policy. Student names are hidden from the projector screen while the QR code is displayed, attendance data is isolated at the professor level so no instructor can access another's records, and all data is transmitted over encrypted connections. AttendanceAF works for any class size at any level — middle school, high school, or college — and exports Canvas-ready CSV files with a single click at the end of every session. AttendanceAF is free for students enrolled in Professor McCarthy's courses at Arizona State University. The iOS student app is coming to the App Store in Fall 2026. @ASU @WPCdean @WPCareySchool #EdTech #HigherEd

I really admired what Harrison Ford said at commencement, especially the part about passion and purpose. Looking back, I don’t think I fully understood it 23 years ago when I first walked onto campus as a professor. But these pictures remind me that somewhere along the way, I found both. I’ve been incredibly fortunate to spend my career doing work I genuinely love — teaching students, building community, supporting ASU athletics, and trying to make a difference for first-year students navigating one of the biggest transitions of their lives. The older I get, the more I realize passion isn’t something you “find” overnight. Sometimes it quietly reveals itself over decades of showing up, working hard, and caring deeply about people. #ASU #ArizonaStateUniversity #SunDevils #HigherEducation #Teaching #Purpose #Passion #CollegeLife #ProfessorLife #Gratitude #WPCarey #Leadership #StudentSuccess #23Years #ForksUp

When no commercial product exists for taking attendance in massive college classes… you build it yourself with AI. Meet AttendanceAF. The “AF” stands for Accountability Focused. Built for large university classrooms where attendance actually matters. QR codes. Fast check-ins. Real accountability. CSV exports. Designed to handle thousands of students without turning attendance into a full-time job. Turns out AI isn’t just changing education… it’s helping educators like me build the tools they always wished existed. #AI #HigherEducation #EdTech #ArizonaStateUniversity #Teaching #Innovation #ArtificialIntelligence #CollegeLife #StudentSuccess #Accountability #AttendanceAF #ProfessorLife #FutureOfEducation #WPCarey #WPCareySchoolofBusiness #Claude #FERPA

23 years at Arizona State… and somehow it just keeps getting better. I’ve had the privilege of teaching thousands of Sun Devils, packing stadiums, building moments that students remember long after the semester ends—and I wouldn’t trade it for anything. This place, these students, this energy… it’s special. And the best part? I’m not done yet. Let’s run it back for 7 more. Grateful beyond words to do what I love, where I love, with people who make it all worth it.

“You can see the surface of the Moon…we just went sci-fi.” On flight day seven, images from our @NASAArtemis II crew amazed, turning science fiction to reality. From the lunar far side to a solar eclipse from the Moon, the views are EVERYTHING. No pressure to pick a favorite.

After 23 incredible years teaching at Arizona State University, I’ve been doing a lot of thinking about the future. Perhaps it’s time for a new challenge and a different shade of red and blue. Right now, I’m reflecting on the thousands of students I’ve taught and the memories we’ve made together. In many ways, this decision hasn’t been easy, but growth sometimes means stepping outside your comfort zone. Looking forward to what’s next… even if it means heading south to Tucson. Fierce rivalries aside, education always comes first. Obviously this will surprise a lot of people, but life is full of unexpected turns. Only time will tell what this next chapter brings. Looking forward to sharing more soon. 😉 #ForksUp #SunDevils #ProfessorLife #CollegeLife #HigherEd #ASU #RivalryWeek #Big12 #CollegeProfessor #UncommonProfessor
