Who is Dr. Lief Sigren?
Lief started teaching at Booker T. Washington's High School for the Engineering Professions (HSEP) in Houston, Texas shortly after receiving his BA from Olivet College in Olivet, Michigan, majoring in biology with a minor in physical education. He taught at HSEP for 11 years before going to graduate school to work on his Ph.D at Rice University. After obtaining his Ph.D., he returned to teaching and now teaches at East Early College High School in Houston, Texas. Being married with two sons, Lief has always enjoyed the outdoors from his early years growing up in Michigan and is truly at home in nature. Over his 21 year teaching career, he has taught IPC (Integrated Physics and Chemistry), pre-AP Biology, AP Environmental Science, AP Biology, and this past year added Physical Education. STEM fits right into his personal life as he likes to camp, hike, fish, and observe wildlife whenever and wherever possible and many of his summers have been spent touring the state and national parks around the country, camping and exploring with his family.
Since 1999 Dr. Sigren has plunged into the use of Information Technology (IT) in teaching, specifically digital cameras, laptops, office toolsets, and authoring software as enabling toolsets that aid in facilitating projects. The process began with the use of digital imagery authoring to document labs and has expanded into multidisciplinary projects including field excursions, documentation of field conditions and in situ laboratory experimentation and research papers.
