Profile Information

Short Bio:
By training I am a data analyst, algorithm developer and neuroscientist. I established labs, worked on academic projects, published articles and books and involved with grant writing.

I managed large multinational and multidisciplinary projects. I involved with project design, risk analysis and matrix management.

When I was working as an academician I realized the gap between scientific projects and technology transfer. I launched TeraStructure which is a technology spin up startup by University of North Carolina. I am trained by biotech and technology gurus and consulted neuromarketing and healthcare startups. I was an invited speaker and consultant for big schools like Harvard and Yale.

I love startups and university spin ups. I am excited to learn new technologies. My interests are in science and management,strategy development and implementation, data analytics and system/business analysis. I help develop grant applications, research and business plans as well as technical methodology: piloting, data acquisition and analysis techniques.

In this note we will create data frames, aggregate and plot.

Let’s start with baby steps and create a small data frame as a new script. You can open a new script by clicking on file and new script. You can copy and paste following…


Quick Review and intro for Budding Analysts: Reading and Aggregating CSV files

Posted on August 25, 2016 at 6:30am 1 Comment

In this note I will quickly talk about csv files on a basic scenario.

I have loaded two csv files with customer complaints on my github account. The complaints are unique and a customer might complain more than once. Customer Id is encrypted as XX000 and assume that missing values don't have the same pattern and number of strings.

After the basic preprocessing we want to know the number of complaints by customers and…


Repost-Leaders Wanted in Data Science Community of Dallas

Posted on October 22, 2015 at 4:51pm 0 Comments

I am an avid runner and have met thousands of runners over 25 years of running around the globe. Regardless of their nationality, pace, endurance and age, runners are the most generous community. They will be selfless to give you the last drop of their water and energy gels. If they see you lost out in wilderness of a trail race they will not think for a second to turn around and add an extra mile to their run (some are competitive runners) to show the right direction getting you to the…
