Problem Solver

Mary Johansson

Areas Mary Johansson is Knowledgeable in:

Fluorescent probes, bioconjugate chemistry, oligonucleotide synthesis, genomic assays, analytical insturmentation, photophysics, physical organic chemistry, electron/energy transfer, biological sensors.

Techniques Mary Johansson Uses:

-I read the scientific literature to get ideas and background information. Sometimes I set a problem aside for a while to get a fresh perspective. Drawing pictures, diagrams, flow charts, building models - all can help, depending on the problem.

Mary Johansson's Problem Solving Skills:

  1. synthesis and spectroscopy of oligosilanes
  2. Electron and energy transfer
  3. Fluorescence assays, FRET
  4. Genomic assays and PCR
  5. solar cells - research and development
  6. Spectroscopy - absorbance, fluorescence, NMR
  7. Oligonucleotide synthesis and conjugation
  8. Biotech research and development
  9. bioconjugate chemistry
  10. adjunct professor teaching chemistry
  11. lanthanide and metalocomplex luminescence

Mary Johansson's Problem Solving Experience:

  1. -I designed and built several pieces of equipment during my Ph D including a variable temperature flow cell with a quartz cuvette.
  2. -I discovered a new quenching mechanism that occurs in dual-labeled labeled probes. This alternative mechanism allows for very high signal/noise ratios in pro-fluorescent assays. This lead to three publications, including one in J Am Chem Soc.
  3. - I wrote a grant proposal for time-gated luminescent reporters and got a 700 K USD SBIR grant. I figured out how to conjugate the lanthanide complexes to oligonucleotides and ran several assays. This lead to a paper in J Am Chem Soc. The technology worked but was too expensive.
  4. -I developed a new fluorescent dye to label oligonucleotides leading to a patent. I worked out the manufacturing protocol, QC criteria, applications development, marketing and customer research. This is now a successful product generating >50K USD in sales.
