My academic profile

My main interest is the study of the interaction between Natural Products and Humans. My main objective is to make sense and make available the ideas, data and materials collected and created by Humans.

I was a visiting research assistant professor at UIC in the Guido Pauli’s lab and the Institute for Tuberculosis Research and a post-doc there before that, for 8 years.

My main research topics were:

  • Making sense, creating sense and inferring sense in Natural Products Chemistry and Pharmacognosy through the Center for Natural Products Technologies - CENAPT
  • HiFSA, Full-spin analysis of NMR spectra
  • Databases on Natural Products (e.g. NAPRALERT), see the section below.
  • Liquid-Liquid Chromatography (CCC/CPC/C?C)
  • Development of tools to ease research (more about this to come)

You can find my list of publications on my ORCID profile or more details on my Publications page.

NAPRALERT

NAPRALERT, acronym of NAtural PRoducts ALERT, is a database created at UIC in 1975 by the late Norman R. Farnsworth. The database aims at being a systematic and curated database of all the research related to Natural Products and Pharmacognosy in general. It includes but is not limited to the coverage of:

  • Traditional use of plants and Natural Products
  • Distribution of compounds produced/present in organisms
  • Distribution of organisms producing/presenting a compound
  • Biological assays in-vitro and in-vivo of organisms, extracts or purified compounds

The new infrastructure

The database was running until 2015 on an aging IT infrastructure that was both costly and difficult to maintain and enhance. This is why Guido Pauli recently appointed director of NAPRALERT, James Graham, its current editor, and I decided that it would greatly benefit from a complete rewrite. A more detailed story is available in my portfolio.

What can be done with it

An example of what can be done in term of advanced data analysis has been described in our Open Access paper: Can Invalid Bioactives Undermine Natural Product-Based Drug Discovery?

We used Python, Jupyter Notebooks, Pandas, Bokeh to clean, treat and analyze the behavior of Natural Products chemists such as their most studied compounds and put in evidence that their behavior is following Power laws.

But many other works from academia and in industry have benefited from NAPRALERT, some can be found on Google Scholar.

Current status

The system has been shut down when I left as nobody was hired to maintain it. I am working on a subset of data from it that will be made open. Stay tuned.
