Eighteen years of industry and academic experience in biological and small molecule drug development.Expertise with a diversity of biological research applications including eukaryotic/prokaryotic protein expression, antigen and antibody preclinical validation, small molecule function and formulations, surface plasmon resonance, signal transduction and in vitro assay development, etc.. Comprehensive experience with both transient and stable mammalian cell culture protein expression, vector design, target validation, and molecular biology. Innovative, adaptable, resourceful and effective at advancing project milestones.Excellent problem solver.Works proficiently in both independent and team oriented projects. Excels in dynamic laboratory environments.


Challenging market conditions increasingly require biotechnology companies to expeditiously evaluate therapeutic candidates. I have the experience and expertise to screen, validate, and manufacture preclinical biologics across a spectrum of hosts and systems.  I will pinpoint and execute those experiments required to identify product leads and navigate them efficiently through the R & D process.

Scientist, Cell Line Development and Molecular Biology

Allozyne, Inc.

¨  Developed a mammalian tissue culture expression platform in HEK293 c18 and CHO cells (DG44 and CHO-S) for site-specific incorporation of nonnatural amino acids (NNAA) into therapeutic IgGs via amber suppression by an orthogonal tRNA-aaRS pair for downstream toxin conjugation (ADC’s) by click chemistry. Demonstrated high yield IgG-NNAA production with manufacturing scale feasibility.

¨Developed an orthogonal tRNA-aaRS pair for site-specific incorporation of NNAA’s in E. coli for the manufacturing of recombinant therapeutic proteins.

¨Expressed, purified, and characterized antigens, antibodies, and antibody fragments used for downstream product development.

¨Developed surface plasmon resonance assays for product candidate validation/affinity determinations.

¨Developed ELISAs used for quantitation and pharmacokinetic analysis of therapeutic candidates.

Ikaria, Inc.

¨Developed flow cytometry assays to assess the efficacy of Ikaria’s technology on blood platelet storage.

¨Expanded Ikaria’s compound portfolio via an in vivo lethal hypoxia SAR screen.

¨Developed a multiwell plate oxygen consumption assay for characterizing compound potency.

¨Characterized a panel of excipients for lead compound stability and formulations development.

¨Optimized manufacturing process of lead compound for In vivo toxicology studies.

¨Evaluated stability of lead compound for FDA required In vitro toxicology studies.

¨Developed a rapid tissue cryopreservation method in rats for measuring lead compound metabolites.

       mammalian expression systems, including CHO and human cell lines.

¨Cloned, expressed, and characterized a modified Her2/neu CHO expressed

      protein vaccine partnered with GSK.

¨Expressed and evaluated multiple forms of an atypical apoptosis inducing anti- 

      GM2 monoclonal antibody and demonstrated that cytotoxicty was dependent on

       specific domains within the Fc.

¨Established HEK and CHO expression models used for antigen and antibody


¨Grew and maintained 30+ adherent and suspension cell lines from multiple 

      species and tissue types.

       Lactate Dehydrogenase (LDH) as the cytotoxicity indicator.

¨Expression Cloned and characterized a novel anti-CD9 apoptosis inducing


¨Trained Research Assistant and supervised project progress for 6 months

    (temporary assignment).

¨Produced large quantities of mIL-4 using an inducible insect cell culture system 

       resulting in significant cost savings to the company.

      (Mnk 1) involved in the regulation of translation.

¨Established a reproducible focus formation assay and analyzed the

       transformational activity of mutations of Ha-Ras.

¨Managed a 10 person laboratory.


Ken Grabstein, Ph.D.

"Jeff is one of the most intelligent and informed scientists I have worked with. He worked for me for many years at Corixa, and I was happy to recruit him to Allozyne. he has a great breadth of knowledge and experience, and conducts his experiments independently and with great care and attention to detail. Jeff is a great employee, and a very pleasant individual, who often contributes very insightful and important ideas in a constructive manner. I would hire him back in a minute, if I could."

Meenu Chhabra

“Jeff is an exceptional team player who has the tenacity to solve any challenge that is given to him. He is a highly creative and self motivated scientist. To that end, his ability to take on challenges and solve them with very few resources is not only entrepreneurial but also establishes a new modus operandii for biotech professionals”

Marcello Marelli, Ph.D.

“Jeff is a creative thinker who has made key contributions to the development of the "biociphering" expression platforms at Allozyne. He is extremely well prepared, experienced and thoughtful of his work and experimentation, and brings a wealth of technical knowledge to each of his endeavors. In addition, he is affable and great to work with, and learn from.”
