Hi, I’m Lorena! I’m a scientist and educator with a PhD in Cell and Molecular Biology, a master's degree in Advanced Genetics, and a bachelor's degree in Clinical Biochemistry. I work at a university as a researcher, though one of my favorite aspects of being a scientist is teaching. I enjoy working with learners of all ages, including helping my own children with their homework and mentoring undergraduate and graduate students in the laboratory. I also enjoy community outreach activities, as they let me share my passion for science and help make it more accessible.

I have mentored over 25 undergraduate and graduate students since 2017 and have served as a lab instructor. My areas of specialty are biology, genetics, cell and molecular biology, and developmental biology; I also provide assistance with scientific writing, research presentations, data interpretation, R, and bioinformatics. Since I am a native Spanish speaker from Mexico, I also enjoy helping students to learn and practice Spanish.

I adopt a patient and encouraging method and adjust it to suit the particular needs of each student. If the material is difficult I break it down into small, manageable steps, use examples and visuals, and am always ready to answer any questions as we proceed. Whether or not we are studying basic concepts or carrying out advanced research, I hope that you not only understand the answer but also know why it makes sense.

Approved Subjects

Biology

Biology

I hold a Ph.D. in Cell and Molecular Biology and currently conduct postdoctoral research in neuroscience, developmental biology, and reproductive biology. My background includes genetics, cell biology, molecular biology, developmental biology, and advanced laboratory and data-analysis techniques. I can help students understand challenging concepts, interpret scientific data, and strengthen their problem-solving skills at the middle school, high school, and college levels. I tailor my explanations to each student’s learning style and connect biological concepts to clear, practical examples.
Chemistry

Chemistry

I have a PhD in Cell and Molecular Biology, a master’s degree in Advanced Genetics, and a degree in Clinical Biochemistry, with academic training in chemistry and biochemistry. My background includes general chemistry, organic and biological chemistry, and the chemical principles underlying cellular and molecular processes. As a researcher and experienced mentor, I enjoy breaking complex concepts into manageable steps and helping students understand the reasoning behind problems rather than simply memorizing formulas. I can help students strengthen foundational chemistry skills, prepare for exams, and build confidence with challenging concepts.
Elementary Math

Elementary Math

As a PhD-trained scientist, I use mathematics and problem-solving skills regularly in my research. I help elementary students build confidence in foundational topics such as arithmetic, fractions, decimals, word problems, and basic geometry. I explain concepts step by step and adapt my teaching approach to each student’s learning style. My goal is to make math understandable, approachable, and enjoyable.
Elementary Science

Elementary Science

I hold a PhD in Cell and Molecular Biology and currently work as a postdoctoral researcher. My scientific background allows me to explain biology, chemistry, earth science, and the scientific method accurately and in age-appropriate language. I help students understand challenging concepts through clear explanations, relatable examples, and step-by-step guidance. My goal is to build each student’s confidence, curiosity, and problem-solving skills in science.
Genetics

Genetics

I hold a PhD in Cell and Molecular Biology and a Master’s degree in Advanced Genetics. My graduate and postdoctoral research has involved extensive application of genetics and molecular biology, including gene expression, developmental biology, and single-cell RNA sequencing. I have experience teaching in a laboratory course and have mentored undergraduate and graduate students in biological concepts, experimental design, data analysis, and scientific problem-solving. I focus on breaking down complex genetics concepts and helping students understand the underlying biological mechanisms rather than simply memorizing information.
Microbiology

Microbiology

I hold a PhD in Cell and Molecular Biology and have extensive experience conducting biological research in laboratory and academic settings. I can help students understand microbiology topics such as microbial cell structure, metabolism, genetics, growth, host–microbe interactions, and laboratory methods. I also support students with interpreting experimental results, reading scientific literature, and preparing for exams. My teaching approach breaks complex concepts into clear, manageable explanations tailored to each student’s level.
Microsoft PowerPoint

Microsoft PowerPoint

As a PhD-trained researcher, I have extensive experience creating polished PowerPoint presentations for lectures, research seminars, conferences, and professional events. I can help students organize information, design clear and visually appealing slides, format charts and images, and maintain a consistent layout throughout a presentation. I also teach practical PowerPoint skills such as using templates, Slide Master, transitions, animations, and speaker notes. My goal is to help students create presentations that communicate their ideas clearly and confidently.
Spanish

Spanish

I am a native Spanish speaker from Mexico with a PhD in Cell and Molecular Biology. I can help students strengthen their Spanish grammar, pronunciation, vocabulary, and conversational skills, with particular insight into Mexican Spanish and everyday expressions. As a bilingual researcher, I understand the challenges of communicating clearly across languages. My goal is to create a supportive environment where students feel comfortable asking questions, practicing, and building confidence in their Spanish.
Thesis Writing

Thesis Writing

I hold a PhD in Cell and Molecular Biology and have completed undergraduate, master’s, and doctoral theses as part of my academic training. As a postdoctoral researcher, I have extensive experience with scientific writing, including manuscripts, research presentations, and communicating complex scientific findings clearly and logically. I have also mentored master’s and honors thesis students through research projects and scientific communication. I can help students organize their thesis, develop a clear scientific narrative, interpret and present results, and improve the clarity and structure of their scientific writing.
TOEFL

TOEFL

I am a bilingual scientist with a PhD in Cell and Molecular Biology who earned a TOEFL iBT score of 106 while applying to graduate school in the United States. Having taken the TOEFL multiple times, I understand firsthand the exam’s challenges and the persistence required to improve. I help students strengthen their reading, writing, listening, and speaking skills while developing practical strategies for each section. As a native Spanish speaker who completed graduate school and built an academic career in English, I provide patient, personalized guidance based on both experience and achievement.
