As a student at UC Berkeley's Bioengineering PhD program, I leverage deep knowledge in the fields of machine learning, biochemistry, calculus, and biology in my research every day. Previously, I developed image analysis pipelines for high-throughput analysis of central nervous system tumors for therapeutic development. I also developed advanced computer vision models at the National Institutes of Health, UC Irvine, and Phi Optics Inc for diverse applications including the neurobiology of aging, predictive epidermal diagnostics, and automated biomanufacturing process controls.

My approach to tutoring centers around connecting the knowledge that a student already has to concepts they are trying to understand. This way, new knowledge is built on well-understood concepts, enabling high-levels of understanding of complex topics. Ultimately, I pride myself in teaching my students to guide themselves independently through new problems so they learn to synthesize their understanding in more complex, unfamiliar situations. I structure my lessons according to Ebbinghaus' forgetting curve, encouraging my students to return to their learning at regular, separated intervals to maximize long-term retention.

I am capable of tutoring a variety of topics:
- High school: I can tutor all topics at up to a high-school level
- Programming: I am adept with Python and have some knowledge of C++, Bash, HTML, CSS, and JavaScript. I have tutored programming for ages 8 to 50+! I am skilled in Computer Vision, GenAI, LLMs, and Protein Models.
- Math: Pre-Algebra, Algebra, Geometry, Precalculus, Calculus, and Differential Equations. I can also help with more advanced math topics if given some prep time beforehand.
- Science: I am an adept tutor for high-school science. Given my PhD-level experience, I can also help with advanced scientific endeavors such as academic publications and experimental design.

If you are interested in an introductory session, please get in touch. I love teaching would can't wait to work with you!

Biology

Biology

I earned my Bachelor's in Biochemistry and Molecular Biology from Oregon State University, where I studied the cellular processes that contribute to brain cancers such as Glioblastoma Multiforme. As a postbaccalaureate fellow at the National Institutes of Health, I studied neurons and performed advanced machine learning-mediated image analyses to study mitochondrial function during aging. I would love to help you with any biology work that needs to be done!
C++

C++

I have taught C++ and object-oriented programming to help students with their collegiate courses. My experience provides students with access to a wealth of knowledge in object-oriented programming, memory and pointer management, data structures, and more. To support students, I break down concepts to their simplest units and walk through for complete and replicable understanding.
Machine Learning/ AI

Machine Learning/ AI

I have been practicing the use of Machine Learning for Biomedical Science since 2022, where I trained a custom, InceptionV3-based computer vision architecture to semantically segment fluorescent microscope images. In my role as a Machine Learning Research Engineer at Phi Optics, Inc, I spearheaded our efforts to develop a machine learning suite in our flagship microscope software to enable real-time cell viability analysis, enabling academic discovery as well as increasing efficiency in bioreactor process control. This led to my current position as an Associate Machine Learning Specialist at the Beckman Laser Institute of UC Irvine, where I support high-throughput instance segmentation and image denoising pipelines for a novel microscope modality designed for skin cancer interventions. Outside of my extensive computer vision credentials, I have experience with generative AI, having earned the Generative AI nanodegree from Udacity as well as built out custom LLM-based tools such as a PEFT-fine-tuned BERT model as well as a Q/A Python Application built using LangChain.

Python

I have been programming in Python for 7+ years. I have tutored Python to students of all ages, developed custom lesson plans, and delivered when helping with pressing projects. I have advanced Python knowledge in bioinformatics through VCF processing at the Earle A. Chiles Research Institute and advanced computer vision experience from working at the National Institutes of Health. Not sure if I can help? Reach out! I'm good at finding solutions to never-before-seen problems.

Chem and English

Alex was extremely helpful in preparing my daughter for her 11th grade English oral. He accommodated each session to the exact issues my daughter was having and gave her constructive feedback and practical tips that helped her improve immensely. She was also able to apply his advice to improve her other English assignments. Thanks to his help, she felt well-prepared and more self-assured during her presentation. I highly recommend Alex to anyone who needs help improving their writing skills or editing their essays. He was also very knowledgeable in helping her with Chemistry. Doing stoichiometry and intermolecular forces.

James, 3 lessons with Alexandre

Patient and very helpful

Alexandre has a very positive attitude and is very encouraging. He helped me through Python exercises. He was very patient in making sure I understood what I was coding and why. I am definitely using him again.
