David S. Ancalle, P.E.
I am an engineer with a passion for fluid mechanics. This field of study has given me the opportunity to work in civil engineering, mechanical engineering, biology, and education. I made this website to share my work and interests with future clients, collaborators and students.
As a water resources engineer, I specialize in water, wastewater, and stormwater design. Some of my recent projects have involved runoff mitigation, sewer modeling, floodplain mapping, bridge design, water quality assessments, and erosion studies. I work mostly in Georgia, Florida, & Puerto Rico but I'm always looking to expand my geographical reach. I am a licensed Professional Engineer (PE) and manage a team of talented engineers and students.
As a biofluids researcher, I study how mammals use fluids for protection, nutrient/waste transport, lubrication, and communication. I like to go where my curiosity takes me, which has led to unusual, interesting, and seemingly irreverent research projects. The interdisciplinary nature of my work has allowed me to collaborate with physicists, chemical engineers, medical doctors, and mechanical engineers.
While I enjoy the work I do, I find it more rewarding to share it with students. I am a teacher at several institutions, and have taught courses in engineering, humanities, and mathematics. I currently teach at Kennesaw State University and at Gwinnett Technical College, and I previously spent a year teaching elementary and middle-school math.
