During my PhD in biomedical engineering, I became an expert in R programming as I used R constantly to organize, analyze, and visualize data. I also have experience helping others learn.

Hi, I'm John! I'm an expert in R programming with 8+ years experience. During my PhD in biomedical engineering, I became an expert in R programming as I used R constantly to organize, analyze, and visualize data. I also have experience helping others learn. I tutored other college students for my college's tutoring center during multiple semesters of college, was a graduate teaching assistant for two classes, and taught R workshops during graduate school. I want to help you be successful at whatever you are doing and to enjoy R programming as much as I do!

I have over 8 years of R programming experience that includes developing R packages and teaching R workshops. I developed two Bioconductor R packages during my bioinformatics-focused PhD which have been published in scientific journal articles. In addition to knowing the R language, I also have experience applying R to analyze big datasets and creating informative, good-looking plots for presentations and papers.

I can teach you the ins and outs of R, from basic to expert. I know programming can be intimidating when you are getting started. If you are new to R, I will be encouraging and focus on helping you gain a better understanding of foundational ideas and practical aspects of R. If you have some experience already, I can help you take your skills to the next level. I have a lot of experience with topics like visualization with ggplot, working with big data using the data.table package, and working with data using tidyverse packages. We can also talk about using R for statistics and machine learning. I can walk you through a topic in R that you are interested in or review your code to suggest improvements and answer questions. I am here to help you so our lesson will be flexible and tailored to meet your goals.

I am a patient and supportive instructor, whatever your knowledge level. Contact me about lessons so I can help you progress on your R programming journey!

Biostatistics

I completed a PhD in biomedical engineering at the University of Virginia. During my time there, I created novel computational methods to understand gene regulation and applied them in the context of cancer epigenetics. I have over six years of experience using R programming for biomedical research. I developed the COCOA and MIRA Bioconductor R packages to analyze epigenetic data, which are both described in published papers.

6-Star Tutor

John was absolutely fantastic when teaching me the coding intricacies related to R in preparation for my assignment. He was extremely knowledgable of the program and was able to communicate the information in a way I was able to understand it. In addition to his expert level knowledge of R, John is very passionate about teaching and really takes pride in making sure his students come away fully understanding the material. I would highly recommend John L. to anyone that is looking for a tutor!

Jake, 26 lessons with John

Very Knowledgable about R & patient

Grateful for all the help John has provided. I have been seeking support on a capstone project with a lot of data analysis skills needed. Because this is not the focus on my program/skillset, it has been very helpful to have someone talk me through some of it. John is so proficient in R codes that he seems able to recite commands like its on the back of his hand. If you're looking for someone calm, patient, and knowledgeable, I recommend working with John.

Awesome tutor

John is a wonderful tutor. We covered R, strings, and coding in several sessions. He is awesome at how he helps students! John is friendly and very knowledgeable. He is easy to work with!

Amy, 10 lessons with John

Knowledgeable tutor

We had introductory lesson to R, which was dynamic, very informative for me and helped a lot to make things clear. Which I find especially useful is video recording of the lesson and copy of the script, so one can refresh the information later. Would love to continue learning with John

Great Tutor!

John is very knowledgeable and patient. I am returning to school (grad) after almost 3 decades so I am a little rusty. John took his time explaining concepts and answering my questions. I highly recommend him!

Outstanding tutor

Great tutor Responds quickly and very easy to plan sessions. He explains concisely and makes concepts easy to comprehend Highly recommend! Definitely a great find.

Lisa, 7 lessons with John

Excellent statistics and R tutor!

John L. did a fantastic job helping with understanding R and stats. I have several learning disabilities and a lot of tutors get frustrated with me, but not John. He did a wonderful job walking me though how to code and showed me a lot of tools that allowed me to figure out difficult situations on my own. He responded fast to my messages and was very available to help me on a deadline. Could not recommend more!

Patient Tutor

I am in my first semester learning R and John was very helpful teaching me the basics while guiding me through one of my assignments. John also taught me helpful tips that I have used in other assignments. Highly recommended.

Knowledgeable and patient

Per my request, John helped me to review the basic steps and principles in working with RNA-seq data. Then, he walked me over a simple GSEA exercise. Overall, he is very knowledgeable and patient, willing to go over multiple times on areas I have trouble understanding. I highly recommend John!
