Naveenkumar Singh, Ph.D.
Downstream Process Development

Naveenkumar Singh received his B.Sc. in Biotechnology (2007) at University of Pune (Pune, India), M.Sc. in Biotechnology (2009) at Jaipur National University (Jaipur, India), and Ph.D. in Biochemical Engineering (2016) at Jacobs University Bremen (Bremen, Germany).

Ph.D. in Biochemical Engineering, with 6+ years relevant experience and a thorough knowledge of the downstream process.

During his Ph.D., Naveen Kumar Singh worked under the supervision of Prof. Marcelo Fernández-Lahore. His research dealt with designing experiments for developing fiber-based and cryogel-based adsorbents for capturing large therapeutic biomolecules (proteins, plasmids, and monoclonal antibodies). He had successfully evaluated the in-house fiber- and cryogel-based chromatographic adsorbents with the commercially available adsorbents and the in-house adsorbents had shown similar or higher productivities compared to the commercial adsorbents.


In February 2017, Naveen Kumar Singh joined the group of Prof. Merlin L. Bruening in the Department of Chemical and Biomolecular Engineering at the University of Notre Dame as a Postdoctoral Research Associate. His current research focuses on developing novel bioseparation processes by introducing polyelectrolyte multilayer films onto membranes/monoliths for the purification of biotherapeutics like monoclonal antibodies.


Skilled in both protein purification for R&D purposes, as well as purification scale-up process development for technology transfer to manufacturing. Highly versed and polished in the execution of downstream multi-steps purification of novel therapeutic proteins to support early phase clinical trials studies. Strong background in the development of protein purification protocols (AKTA-based protein chromatography) at small and larger scale. An AKTA/UNICORN expert across all models and software versions. Experienced with protein analytics, UF/DF, filtration, and formulation.

Ph.D. in Biochemical Engineering
Jacobs University, Bremen, Germany

Thesis: “Preparation and characterization of grafted adsorbents and their applications in biomolecule purification”.

Supervisor: Prof. Dr. Marcelo Fernández-Lahore.

Within this project, Hybrid Disposable Cartridges (HDC), a hybrid approach created by merging existing textile technology with Material/polymer chemistry was used to generate a cost-effective and disposable system supporting eco-friendly bioprocessing.

The goal here was to evaluate the performance of gPore NW materials, which can be functionalized and used to purify a range of bioproducts efficiently.

The further objective was to tailor the gPore NW system, which has already shown excellent results in the recovery and purification of natural as well as recombinant proteins, to other products, like pDNA or monoclonal antibodies.
