Certified Tutor
About Me
Bilingual STEM tutor (EN/ES) with 7+ years of experience helping middle-school, high-school, and college students turn confusion into confidence. I'm currently pursuing a Ph.D. in Civil, Environmental, & Sustainable Engineering at Arizona State University. I hold a B.S. in Biochemical Engineering (focus: wastewater treatment) from the Technological Institute of Mrida and an M.S. in Renewable Energies (bio-based technologies). I've also spent ~4 years tutoring with Varsity Tutors and leading workshops, museum visits, and science-fair coaching.
Subjects I Tutor
Math: Pre-algebra Calculus, Differential Equations, Statistics
Physics: Classical mechanics, biophysics, instrumentation
Chemistry: General, Organic, Inorganic, Analytical, Physical, Biochemistry
Biology: Anatomy, Microbiology, Ecology, Genetics
Specialties: Environmental engineering/biotech, wastewater treatment, renewable biological systems
How I Teach
First principles + guided inquiry: I break problems into core ideas and ask targeted questions that reveal gaps and build true understanding.
Active practice: We solve representative problems step-by-step, then I fade support so you can perform independently.
Custom plans: Quick diagnostics focused roadmap measurable milestones.
Clear takeaways: Every session ends with a short recap, a mini-cheat-sheet, and next steps.
