Where we are:
McCann's main base is in Northern Delaware, USA, but there are strong links to the UK where we have a home base and clients too.
Washington DC, Philadelphia PA, Trenton NJ, Baltimore MD, Arlington VA, Camden NJ, Wilmington DE and New York NY are all easy to get to. Using Philadelphia International Airport (PHL) gives access anywhere, though we find much of the work can be done remotely using the internet saving travel costs.

Examples from consulting experience.
Chemical: Fermentation (antibiotics, stoichiometry and metabolic pathways), polymers, reaction kinetics, distillation, heat exchange, mass transfer, emulsification, supercritical fluids in any sort of distributed parameter system. Control systems and heat transfer instrumentation. Flow allocation for a toxic gas.

Electrical & Electronic: Electromagnetic compatibility (EMC), electromagnetic interference (EMI), electrostatic discharge (ESD), dielectric breakdown and lightning. Safety of pyrotechnic (explosives) initiation systems. Microwave antennae, RF soldering. Management of design and development. Transmission Line signal propagation.

Production & Process: Vacuum web coating (metalization), paper making, glass making, molding and heat treatment, plastics extrusion, injection moulding (molding) high temperature plastics. Operation and productivity of automated manufacturing. Resource allocation and planning. Flow allocation of a toxic gas. Crimp and Press operation. Many applications involve heat transfer

Market & Economics: Marketing of pharmaceuticals, paints. Automobiles, construction / building industry, retail security, value of advertising,  decorative wallpaper & paint,

Business: Corporate cash flow dynamics, internal demographics. Planning, capital investment, international research and development strategy

Tools: These models, simulations and other solutions have been developed in a range of programming and simulation languages, including Mathcad (from MATHSOFT) and a special tool McSimAPN , based on years of experience to be able to quickly and graphically develop models for both continuous systems simulationand discrete event simulation in the same package. We can also do engineering drawings (CAD using AutoCAD etc) either as a separate project or linked in to computations.
