Currently teaching Biology, AP Experience Biology, AP Environmental Science for grades 9-12th graders at Walter Johnson High School. I sponsor Gardening Club and participate in other capacities within the department. At Silver Spring Middle School, courses in life sciences in the IB (International Baccalaureate) MYP (Middle Years Programme) to students within a global context and within their own community. I was the lead teacher for 7th grade cohort. We coordinated curriculum, labs, assessments, and activities. I was leading the Field Trip Committee where we plan outdoor trips to enrich and enhance student curriculum.

• Maintained high levels of confidentiality to protect data quality and project research.
• Followed best practices and scientific protocol to gather defensible data based on solid evidence.
• Maintained live organisms including breeding, end-of-care and substrate, solutions and feed
• Applied research technique to determine effectiveness of specific compounds and possible interventions.
• Collaborated with other researchers to determine impactful results of biological research.

Courses taught: Honors and Regular Biology, AP Biology, Environmental Science, and Genetics. Incorporated case study method for relevant and engaging science learning for grades 9-12. I integrated personal response systems for formative assessments to monitor and revise science instruction. I sponsor the Ecology Club, Interact Club and Science National Honor Society for students to participate, help and learn within their own community and as citizen scientists. I use a variety of wet-labs, virtual labs and computer simulations to help students grasp difficult and advanced science topics

As an adjunct, I instructed 40-50 students via an online course delivery system with real-time tutoring, assessment and communication. I had daily contact with students and parents to monitor progression, help with material and assist with online learning. I kept a lively, manageable pace with students to maximize completion for credit and credit recovery.

As a lead teacher (2010-2011) I provided professional development and mentoring to new teachers relating to science and general best practices. I was also involved in the accreditation renewal process. I was the AVID science lead at Cypress Creek (2005-2010) and an AVID trainer for Orange County Public Schools (2009-2011). I was also in charge of science chemical inventory and safety (2008-2011), helping keep in compliance with Federal OSHA and Florida DEP laws. Courses taught include Integrated/Physical Science , Biology Honors and Regular, AP Biology and AP Environmental Science. I planned and conducted hands-on inquiry based science activities to provide students with opportunities to observe, question and investigate.

• Performed routine data analysis to correct and verify data entry.
• Assessed data using scientific methods while following important specifications.
• Maintained safe, organized working environment by following protocols in field data collection
• Used Excel and SPSS to prepare and manipulate extensive databases.

• Maintained Zebrafish experiments and husbandry and documented all relevant water quality data, schedules, chemical stock and laboratory maintenance
• Worked both independently and collaboratively in fast-paced laboratory environment.
• Performed statistical, qualitative and quantitative analysis.
• Worked with principal investigators to coordinate qualitative and quantitative research into PFOS toxicity and mutagenic effects on Zebrafish embryos.

As a reader, my responsibility was to score the free-response submissions of AP Bio students according to established rubrics and my expertise. I worked in sync with the table leaders and head reader to include additional language or clarifications to ensure accurate and consistent scoring of student work.

I judges numerous Division B and C events at regional and state competitions, I am a current coach for my high school team since 2016, and from 2006-2011, I was managing all the STEM events for the regional competition including 26 events, 45 high school teams, 50 judges and 60 volunteers.

I was part of the committee that reviewed future test items on the National Board Examination for Biology. We tested for scientific accuracy, free of bias, reflective of knowledge and skills required for accomplished teaching consistent with the National Board's Educator standards and practices.
